Post WWII watches and the birth of the NATO strap


Introduction

In earlier articles the predecessors of the NATO strap were reviewed.

Some military watch specifications were in the process of revision after some years of experience in the field, and the need for more advanced watches was revealed.

The W.W.W. watch for the British army was a revision to the ATP watch, released at the end of WWII, and surplus watches were de-stocked back into the civilian market. Advanced navigation and dive watches were being planned, and were specified after the end of the war.

Also, after the end of WWII, political considerations led to the NATO military alliance, and all issued military equipment of members and associates of NATO, including watches, and straps, had an identifying NATO stock number (NSN).

One such strap, more than the others, has had its NATO NSN shortened by common usage to just NATO.

The NATO Stock Number

WWII revealed the need to coordinate the supply of military equipment, particularly when joint forces were in the field together.

stores

The Vocabulary of Army Ordnance Stores (VAOS) was the British Army system of cataloguing parts.  The Director of Stores maintained notes on all the in service equipment and kept track of changes in patterns of equipment and stores. This list was updated and circulated on a regular basis.  The Vocabulary publication, which in the later years of its use was amended quarterly, required that units use the exact nomenclature that appeared in the Vocabulary. The Vocabulary system was used by the British Army for close to ninety years until it started to be displaced by the NSN system in 1956.

With the formation of NATO in 1949, common numbering systems were developed for items of equipment.   This system was based on the US Federal Stock Number (FSN), which itself commenced in 1953.   In 1974 two additional digits were added (the national identifier), and in US this became the National Stock Number.

In all 64 other NATO affiliated countries this number is referred to as the NATO Stock Number (NSN), and has 13-digits, the first four indicating the group and classification of similar supply military items. The next two digits correspond with the country code of NATO member states (12 is Germany, 99 is Great Britain, 00 or 01 is USA). The last seven digits describe the exact object.

NSN

The NSN, or NATO Stock Number is most easily explained in the above diagram.  It commences with a NSC, and then a NCB, together with a 7 digit number.

The NSC for "Time Measuring Instruments" is 6645.  The first two digits, called the Federal Supply Group (FSG), define the overall category of the item.  In the case of most issued watches, that is “66 – Instruments and Laboratory Equipment.”  Adding the FSG to the next pair of digits – the 2-digit Federal Supply Class (FSC) – narrows the item category even more.   For military watches, that becomes “6645 – Time Measuring Instruments.” 

In the illustration above, the classification category code 1005 is "Guns, through 30mm", 13 is Belgium, and the other non significant numbers are meaningless.

Some 13 million items are identified with a NSN.

USMC Korean War watches

(Spec : Watch, Wrist, Seven-jewel?)

The US Marine Corps sourced new watches in about 1949, which were very similar to the ORD DEPT watches of WWII.  These included the Bulova 1917-H and the Hamilton 747.   They were stainless steel, and the major external difference was the sub-seconds dial where the numerals are oriented horizontally. The end of the blued seconds hand was enhanced with a luminous ball.  Below is a Hamilton 747 on the right, with an ORD DEPT Hamilton on the left.   The specification for this watch is unknown.

The A-17 and A-17A Navigation

(Spec ; Watch, Wrist ; Second Setting)

During WWII improvements were sought to the A-11 watch, and manufacturers produced some prototypes, as the improvements were largely dial related.   As occurs often in product development, did the prototype proceed the specification? Nevertheless MIL-W-6433 of 1950 describes the requirement for the A-17, with essentially much more luminosity, and a 24 hour dial when compared to the A-11.

The Bulova and Elgin A-17A models were produced later to MIL-W-6433A of 1954 and overlapped, from approximately 1956 for the Elgin, and 1958 for the Bulova.  An April 1957 model Elgin A-17A shown below was provided on the moulded nylon strap ORDNANCE DEPT. USA  PART NO. 7646909, as specified in MIL-S-3035.

The RAF Mk.11 watch

(Spec. Wrist Watch, Mk.11, Navigator's)

After the war, having used the USAF A-11 in the RAF 6B/234 designation, the UK MoD also independently modified the A-11, and issued the 6B/346 specification in late 1946 or early 1947.  

The specification called for a watch which was very similar to the A-11. The main difference was that chronometer-grade performance was specified, along with anti-magnetic properties.  (Type A-11 wristwatches were manufactured in accordance with military specification 94-27834, published in 1940).

The resulting watch, the 6B/346 Mk 11 “Navigator’s”, was produced by two companies, Jaeger-LeCoultre (JLC) and International Watch Company (IWC), and was issued to RAF and RAAF forces from 1948 to 1953.   The JLC watch was not a success compared with the IWC watch.

The 6B/346 had fixed bars and originally came on a 17.5mm clip stainless steel BONKLIP bracelet (6B/2763).  The RAAF models had spring-bars and were coded G6B/346. The BONKLIP strap could be closed at different positions which allowed it to be fixed at variable lengths, over or under a flying suit.

Every item of RAF equipment had a Store Ref. No. assigned, not only to the watch itself, 6B/346, but as well the BONKLIP straps. As three different versions of the BONKLIP were used by the RAF,  namely 6B/2763 (17.5 mm in width designated to be used with the Mk 11, 6B/3224 (19.0mm in width) and 6B/3033 (20.0 mm in width). The last two to fit the chronograph 6B/551 H.S 9. and the Watch, Wrist, General Service 6645-99-910-1000 or 6B9101000.

Howlitt patent bonklip

D.R. Howlitt applied for, and was granted the patent on the Bonklip strap in 1930 in both England GB349657 and later in Germany 577586 drawing above.

An American patent application US1779068A was earlier filed for virtually the same design on April 10, 1929 by Walter M. Krementz, but this Staybrite strap was expensive and not as popular as the Bonklip.

In Australia in 1951 about 2000 replacement watch straps meeting US Military Specification, Strap, Wrist Watch, Nylon, MIL-S-3035 (dated 8 September 1949) were imported for the RAAF.   Drawing B7646909 specified the one piece moulded strap, shown below.  With this type of strap, if one spring bar was lost, the watch would still remain on the wrist.

mil spec strap

In 1954 a nylon NATO strap (6B/2617) was introduced by the RAF to replace the BONKLIP.  As this band was very long, its length could be varied easily.  However, the BONKLIP had advantages, and they were re-introduced by the RAF in 1956, allowing the BONKLIP or the nylon strap to be used alternatively.   (Ref 1)

The DEF-3 Specification, watches and strap

(Spec : WATCH, WRIST, GENERAL SERVICE)

Ministry of Defence specification DEF-3 (provisional) dated 1 September 1951 was superseded by DEF-3-A dated 20 October 1959 for Wrist Watch, General Service for the British military.   DEF-3-A stipulated the Joint Service Number or NSN 6645-99-910-1000 for central sweep (non hack) watches to this specification.

The Omega 1953 (CK2777-1) purchased by the MoD for the RAF in 1953 was built to the DEF-3 specification.  It uses the Omega 283 caliber. The watch was to be issued on a DEF-3 strap.   The specification for the strap is given below, and as shown below, it has no preformed holes for the buckle tongue.

Omega 53The case back of the Omega 1953 is shown above.  The NATO Stock Number NSN was in its infancy and only  6645 101000 is engraved on the case back. The RAF stores reference code was 6B/542, and xxx/53 was the serial number. 

In 1956 the GS Smiths Deluxe Cal. 27CS wristwatch was also supplied under the DEF-3 specification. The RAF GS Smiths Deluxe had the caseback marked with 6B/542 or 6b/542 designation, 
and NSN 6645 101000.  The Directorate of Overseas Surveys (D.O.S.) GS Smiths DeLuxe Cal 27CS caseback of 1959 or so, has D.O.S. and the full NSN 6645-99-910-1000 engraved.

Here is a Smiths Deluxe GS watch on a period VB Hygienique NATO strap.

In 1965 Hamilton provided a general service watch to the RAF.  This was supplied under DEF-3-A and was non hackable.   The watch was built to a similar specification to the Mk.11 watch and is sometimes called the Hamilton Mk.XI.  The watch is 6B-9101000.

The image below shows the watch and a sewn webbing strap.

Hamilton 6b-9101000

 

DEF-3-B dated September 1966 covered hackable central sweep watches to this specification, and stipulated the Joint Service Number or NSN 6645-99-961-4045. The B revision required “inclusion of a device to arrest and release the second hand”.

The General Service Smiths W10/6645-99-961-4045 (model GS4701) was issued from 1967 to 1971 under DEF-3-B, and used the DEF-3 strap.  The RAF version was engraved  6B-9614045.   Hamilton also made a model 6B-9614045 H-67.

A Hamilton watch on a DEF-3 strap is shown below, with the characteristic doped tip.  The buckle and keepers are stainless steel, but this buckle is shouldered, like that of the A.F.0210. strap.  The webbing is tropicalised to specification NF203/7, and the buckle tongue penetrates the strap to make the positioning hole. 

DEF3 strap

Commonly the older A.F.0210. webbing strap was used.  This was part of the revised 1944 or 44 pattern webbing issued as A6/AFxxxx, Jungle Equipment, for use in the far east. The A.F.0210. strap was a precursor to the DEF-3 strap above, with almost identical dimensions, but used folded webbing stitched all round, with a square end, and brass buckle and keepers.   The A.F.0210. strap and DEF-3 strap sometimes had virtually identical hardware, but the latter in stainless steel, not brass.

AF0210 strap with 6B/2593 compass on AF0034 pamphlet.

 

When the 44 pattern Jungle Equipment was introduced in 1945, a lightweight aluminium frame that could be configured to carry various loads was one of the many new innovations.   The complete frame was AF0034, Carrier, Manpack, General Service, and weighed 1.7kg.  Instructions for use are shown above, together with the AF0210 strap and a 6B/2593 compass.

The various components of the AF0034 manpack carrier were given stores numbers to allow for replacement components.  The ladder frame is reference AF0083, and the removable load board is AF0084.  The four bearer tension straps (marked AF0087) provide a large cushioned area for comfort.  The waist strap is marked AF0088.   Frame brace straps are AF0086.   The manpack carrier also has two simple shoulder straps with wider shoulder sections for comfort and attached to these is a chest strap to help secure the load.  The shoulder straps are stamped with AF0091.  The two part chest strap is AF0085.  The reverse of the manpack carrier has two adjustable straps with 44 pattern style double buckle fasteners for securing loads to the frame, labelled AF0090. The fastenings are all in the same rust proof metal as used in the 44 pattern webbing set.

Below is an A.F.0210. strap with a 6B/2593 compass, and a A.F.0225 rectangular mess tin.     The mess tin is also marked MMS1945 and is also part of the 44 pattern webbing jungle system, A.F.xxxx issued in 1945.

As earlier VAOS nomenclature for military equipment was reclassified under the NSN system the A.F.0210. strap finished it's service life under NSN W10/6645-99-910-1003, Webbing, (Spec : STRAP, WRIST, INSTRUM).   

W10 is the section of the Vocabulary of Army Ordnance Stores that includes magnetic compasses, drawing and optical instruments, watches, survey, hydrographic survey and underwater sound equipment.  

Later A.F.0210. buckles and loops were selenium dioxide treated to make black (bonderised?).

A service life of some 35 years makes this a classic strap, and the influence which it had on the design of the NATO strap can be seen in the similarity in design of the NATO strap below.

The nylon NATO strap, seen earlier as 6B/2617 was specified by the military from at least 1973 onwards, under under NSN 6645-99-124-2986.     It is 280mm long, compared with the A.F.0210. which was only 250mm long, with the design change acknowledging that wrists were becoming larger.

Despite predating the DEF-3 strap, and the NATO strap, the A.F.0210. strap was not discontinued, and remained in service alongside the DEF-3 strap, and the NATO strap, until taken out of service in February 1980.  Below is the order replacing it with the NATO NSN 6645-99-124-2986 (Nylon).

The Bulova General Service

(Spec : Watches, Wrist (all Grades))

Bulova provided the A-17a navigation watch above, and also similar general service watches to the MIL-W-3818A specification.  The MIL-W-3818A specification covered 3 grades of GS watches, Grade I +/- 10 sec/ day,  Grade II +/- 30 sec/ day, and Grade III +/- 60 sec/ day

The MIL-W-3818 specification of 24 October 1952 was revised to the MIL-W-3818A specification dated 12 March 1956.   Figures 1 and 2 of the specification provide for a sub second, and sweep second dial respectively.  

Bulova provided two sweep second watches to the MIL-W-3818A specification with a 10BNCH movement, a 12 hour to Figure 2a, and a 24 hour to Figure 2b.   The 24 hour dial is very similar to the A-17a dial, but the hour hand is heavy spade shaped.  The strap was specified to be MIL-S-3035 Strap, Wrist Watch, Nylon of 8 September 1949.

A NOS cordovan strap is shown below with a Bulova MIL-W-3818A.

MIL-S-3035 Strap, Wrist Watch, Nylon reads in clause 3.3 :

3.3 Design and Construction - The strap shall be manufactured in accordance with Drawing B7646909. It shall be of one-piece construction with integrally moulded loops. Sewing, cementing or heat sealing shall not be used in the construction of the strap. 

Strap 7646909

 The strap came in black or Cordovan/brown.

MIL-W-3818B specification dated 17 October 1962 revised the title to Watch, Wrist : DTU-2A/P and revised the dial, and the strap requirement.

Clause 3.8 reads :

3.8 Strap.  The strap shall be fabricated in accordance with Drawing C 8636227.

However, an interim amendment of 12 January 1966 substituted :

3.8 Strap. The strap shall be Type II as specified in MIL-S-46383.  The color of the strap shall be black.

Benrus provided these MIL-W-3818B specification watches to the military.

Perhaps due to the rigid nature of the  MIL-S-3035 straps, many MIL-W-3818A watches are seen on MIL-S-60127 straps.

Tornek-Rayville, TR-900

(Spec : MIL-W-22176A, MILITARY SPECIFICATION: WATCH, WRIST, SUBMERSIBLE (400-FOOT), NON-MAGNETIC)

MIL - W - 22176 A (SHIPS) of 24 March 1961 replaced MIL - W - 22176 (SHIPS) of 1 September 1959, and was for an amagnetic 400 foot deep capacity diver's watch.  The US Navy specification for submersible watches was strict and only one manufacturer could meet the requirements

Allen Tornek, who was then importing pieces from the Rayville Watch Company who were already manufacturing a diver’s watch, the Blancpain ‘Fifty Fathoms’ bid for the contract, and produced the Tournek-Rayville. 

Only 1000 watches were produced, and many have been destroyed as radioactive waste, so maybe only 20 to 30 currently survive. 

The MIL - W - 22176 A (SHIPS) specification required :

3.9 Strap - Each watch supplied under this specification shall be equipped with a one-piece nylon strap conforming to the specification MIL-S-21382, and which has met the magnetic test requirement of that specification.  

Mil spec 50 fathoms

 

Above is the dial diagram included in the MIL-W-22176A specification requirements (left), and the Tornek-Rayville instruction manual, showing the proposed light grey woven nylon strap (right).

The watches are commonly referred to as “Tornek-Rayville”, “TR-900” or sometimes just as “Tornek”, as these are the markings seen on the dial and on the movement. The initial order delivered to the US Navy was for 780 pieces in 1964 and another in 1965 for 300 pieces giving a total of just over a thousand for this model.

 The as issued tubular weave strap is shown below.

tournek rayvilleTournek Rayville strap

MIL-S-21382(SHIPS) is for STRAP, WRIST INSTRUMENT, WOVEN NYLON and was issued on 21 August 1958.

The specification requirements were for an 11 inch, light grey herringbone weave nylon strap, with an 1/2 inch wide keeper of the same material fused to the strap.  Also, "the buckle shall have a dull nonreflecting finish and be free from burrs."  

In 1963, before the first watches were supplied, MIL-S-21382(SHIPS), was subsumed into MIL-S-46383, STRAP, WRIST: INSTRUMENT of 20 July 1963. The strap became the Type I - Strap, Special Purpose: Non-Magnetic Buckle of the 46383 series of specification issues.

The strap colour grey changed to black with the specification change.

 

Antimagnetic strap

Above is the Type I special purpose strap drawing from MIL-S-46383.  The dimensions are as for the MIL-S-21382 specification strap, and the length allows the watch to be worn over a diving suit.

 

The NATO strap NSN 6645-99-124-2986

(Spec : Strap, Wrist Watch)

The nylon NATO strap, seen earlier as 6B/2617,  was specified by the military from at least 1973 onwards, under under NSN 6645-99-124-2986, and from 1992 there are actually two NATO stock numbers allocated to this item: Army/Navy NSN 6645-99-124-2986 and RAF NSN 6645-99-527-7059.

Through common usage, the full NATO NSN 6645-99-124-2986 for this strap is abbreviated to just NATO strap.

The current Defence Standard specification illustrates the requirements of this strap.   It was initially specified in Def Stan 66-15 (Part 1) Issue 1 – Strap (Nylon) dated 30 November 1973.

NATO Strap

 

The commonly called NATO strap has several written characteristics, and probably many more unwritten characteristics.

The actual military specification strap comes in only one colour (Admiralty Grey) and one width (20mm). The hardware specification is chrome plated brass with a recessed buckle to receive the tongue.   Length 280mm, width 20mm, thickness 1.2mm.

It is currently defined in Ministry of Defence, Defence Standard 66-47 as Strap,Wrist Watch.  

Wrist watch strap

 

Earlier, there was a nearly identical NATO style strap made in accordance with DEF STAN 66-15 (PART 1) Issue 1, Strap (Nylon), 30 November 1973.  It was specified as grey as well, and it was used (under NSN 6645-99-124-2986) by the Royal Navy and British Army from 1973 until 1992 when the NATO standard DEF STAN 66-47 (ISSUE 1) superseded it. 

For soldiers to obtain a NATO strap, they had to fill out a form known as the G1098, or G10 for short.    Sometimes these straps are known as G10 straps, as they were used on W10 watches.

US Military NSN 6645-00-333-5396

(Spec : Strap, Wrist : Instrument)

By contrast the US Military NSN 6645-00-333-5396  Strap, Wrist Instrument  ; Plastic Polyamide, is just a pass through strap, manufactured according to military specification MIL-S-46383B Type II.

MIL-S-46383A Strap, Wrist: Instrument was issued on 1 June 1965, and superseded by MIL-S-46383B on 16 September 1970.

 

46383 strap

This requires a black strap with a buckle assembly which shall be black oxide coated and painted with a dull black enamel finish.  The strap is of one piece construction 9.750 inches long, 0.625 inches wide and 0.045 inches thick. The strap has a keeper loop to receive the strap end as shown below.   The specification allows for other colours than black to be procured.

MIL-W-46374 specification was issued in October 1964 to procure a low cost, disposable alternative to the MIL-W-3818B. The specification provided for either metal or plastic sealed cased watches with minimal shock or water protection, and a lower accuracy, and a non-hacking movement.  Specifically the strap was to be olive drab.

3.3.5 Strap. - The strap shall conform to the requirements of MIL-S-60127.

This Specification was later revised, and required fixed bars, and an olive drab pass through strap, manufactured according to military specification MIL-S-46383B Type II.

3.2.4.6 Strap. - The strap shall be in accordance with MIL-S-46383, Type II. The color of the strap shall be olive drab matching color number X34087 of FED-STD-595.

The 7A28-7120 GEN. 1 RAF

In the mid 1980s, Seiko released its 7A28-7120 variant with reference number SPR047 and NATO Stock Number (NSN) 6645-99-768-3056 to be used by the Royal Air Force (RAF).

The MoD bought and issued a total of 11,307 these Gen 1’s, which makes it one of the most popular issued military chronographs to date.

It should seem obvious that NSN 6645-99-768-3056  (Chronograph, Wrist ) should be compatible with NSN  6645-99-527-7059 (Strap,Nylon/Leather, Wrist Watch).

Here is such a combination.

NSN 6645-99-527-7059 (Strap,Nylon/Leather,Wrist Watch DEF STAN 66-15 (PART 2)) illustrates the Specification for a brown RAF strap.   This is the Kitchener style strap from WWI.

These brown combination leather straps were the standard RAF strap from the early 1970's until the 1992.  Therefore, a properly dressed Gen 1. RAF Seiko Chrononometer should sport one of these rare Kitchener NATO straps.

Variations to the Strap, Wrist Watch specification

From the earliest time at which men fought in organised companies, the corps have possessed some sort of insignia visible over all the field of battle, serving as a rallying-point for the men of the corps and as an indication of the position of the leaders.

All military Regiments have had ribbon and patch colours based on their battle flag or colours.

 

Regimental colours

Variations in colour for NATO straps derived from another military tradition, that of stable belts.

Originally, stable belts were worn by the cavalry in the working dress they used for stable duties, but in the 1950s they spread to all branches of the armed forces, adding a splash of colour and individuality to the khaki working uniforms. Initially they were resisted by many senior officers, who saw them as too individualistic, but due to Regimental rivalry they soon became accepted throughout the forces.

As an example, the Royal Marines stable belt is shown below.

This is worn over the barracks dress jacket.

Royal Marines  stable belt

The NSN for a stable belt is simply NSN: 8440-99-571-2693 Belt.   However military uniform suppliers soon produced Regimental stable belts.

When worn without the jacket, but with NSN 8405-99-983-1241 Trousers, Mans, Barracks Dress,Army All Ranks, khaki it is worn through the belt loops.

The availability of woven nylon in various colours soon led to British Military Regiments ordering NATO straps in regimental colours, again from specialty outfitters.

Above is the Royal Marines NATO strap on a NSN 6645-99-541-5317  Watch, Wrist.

Today, every Regiment  of the British Army has its own stable belt, together with its own NATO strap, often very colourful, to go with the regimental tie (NSN 84440-99-874-6348 Tie, Regulation)
