Breguet Type 20 Generation 1 Military Issue


Breguet Type 20 timelineTimeline above includes both Civilian and Military models

Montres Breguet was founded in 1775 by the great inventor and clockmaker Abraham-Louis Breguet (1747-1823), and had its headquarters in Paris until it moved to Switzerland in the 1970s.

After WWII the French military Ministry of Defence issued a specification, Type 20, for aviator watches, and asked manufacturers to respond to the tender.

Breguet was on such responder, and won the tender for a large number of the watches.

Six manufacturers were selected to supply these watches with four still making and selling watches: Breguet, Dodane, Auricoste and Vixa. The brands Airain and Boullier have not survived.[1,2,3,6]

The Breguet Type 20 Generation I military series was born in 1954.

This article covers the first generation of the model and its use in the French Military. Another article will cover its civilian twin, and the evolution to later generations.

The Type 20 Specification

No accurate edition of the Type 20 specification exists, but consensus is that the watch should have the following.[1,2,3,7]

A black dial adorned with easily readable Arabic numerals and luminescent hands and indexes;

a seconds chapter ring;

a screwback case of about 38mm and less than 14mm thick;

a bi-directional rotating bezel;

a mechanical self-winding chronograph movement with a power reserve of 35 hours;  accuracy to within eight seconds per day;

a flyback mechanism;

and evidence that the watch is able to support more than 300 times starting, stopping and resetting the chronograph.

The crucial feature the French government requested was the flyback for the chronographs. The flyback function of the chronograph allowed pilots to reset or retour-en-vol timing by pressing the lower push piece.

The need for improved reliability and maintenance gave birth to the Type 21 in 1956.[12]

Type 21 specification

Breguet had produced chronographs from the early 1930’s and these supplied design ideas and style to the Type 20 model. However, the French military as part of war reparations were already using German supplied Hanhart and Stowa watches, and were familiar with design features, which would have fed into the Type 20 specification.

Hanhart had earlier supplied pilots in the Luftwaffe, and there are strong design similarities between the 1950 Hanhart and the Type 20 Breguet.

The Breguet  4174 case type was also a precursor to the Type 20 model.

 Breguet Type 20 5101/54 model – AIR FORCE

The standard model for the French Air Force is shown below. It was a 2 register model, with a 30 minute sub-register, and almost universally was fitted with an unsigned dial, characterized by a gorgeous onion crown.

The Type 20 5101/54 model had a Valjoux Cal. 222 mechanical movement, 17 jewels, black matte dial, luminous Arabic numerals, outer second/minute divisions with Arabic numerals, luminous skeleton baton hands, skeleton propellor sweep second hand, two subsidiary dials, one a 30 minute register and the other showing constant seconds, circular stainless steel case, stainless steel bezel with reeded edge and arrowhead indicator, two round chronograph buttons in the band, onion crown, downturned lugs, and a screw back case.


Breguet Type 20 5101/54

Delivered to the  French Air Force  on 1 October 1956 this watch has baton hands with long thin pointers at the tip. The numerals 4 and 7 have a unique style. This model does not have an onion crown, which may have been replaced during service.   Note the tiny BREGUET logo at 12 o’clock, perhaps an attempt to carry branding on the dial, despite the Type 20 specification.

In 1954, Breguet was commissioned to produce 2000 Type 20 watches, and the casebacks were engraved “Breguet, Type 20, 5101/54” for the contract number and year. As Breguet needed to produce a large number of watches in a short amount of time, production of the watches was contracted out – Breguet used the Valjoux 222 movement, and the watches were assembled by Mathey-Tissot.[3]

Later, Breguet would produce their own civilian version, with their name on the dial and slight variations, including three registers on the dial.

 Breguet Type 20, 5101/54, No. 7562

This version had different style 4, and 7 hour markers, and the open 6 marker.

Breguet Type 20 Case number 7688

This model has a differently maked 30 minute sub-register. Case number 7688. Delivered to the Air Force on November 16, 1955.

The Breguet-produced watches for the French military were given to the Armée de l’air (French Air Force), 2000 pieces from 1954, Aeronautique Navale (Aeronavale, French Naval Airforce), 500 pieces ordered in 1958 but delivered from 1959 onwards [3], and Centre d’essais en vol (French Flight Tests Center), also known as CEV .

The Type 20 delivered to the Air Force differed from the version for the Naval Aviation. This version has an internal protective anti-magnetic housing and a 15 minute sub-dial.

CEV had two different versions (a two register (500 pieces 1960),  and three register (50 pieces 1960) ) both equipped with  a 15 minute sub-dial.

Breguet Type 20 Military Timeline

A quick look at the Breguet Type 20 Military issues produced from 1954-1960

These watches needed to be inspected for accuracy and after each inspection, the date of the next scheduled examination was engraved on the back with the letters “FG” – Fin de Garantie, end of warranty.   The FG dates can be seen engraved on the case above. [3]

All these chronographs were  overhauled and their precision controlled by the Dodane company at the Service Officiel de Contrôle de la marche des montres de Besançon (CETEHOR).

The servicing wasdone in the workshops of Besançon and Paris (mainly Dodane and Pechoin). Dodane was probably the largest supplier of Type 20 models to the French military. [12]

The Type 20 watches were used by the French military through the 1980’s, and were often replaced by quartz models.

In parallel to these official orders, Breguet also offer civilian versions of its Type 20 and  some 2,000 chronographs were  sold between 1954 and 1970 to civilians.

Type 20 Aeronautique Navale

All the 5101/54 models above had 30 minute sub-registers.   The dial was generally unsigned.

When issued to the Aeronautique Navale, this Navy watch was identical to the 5101/54 model but was signed Breguet on the dial and had a 15 minute sub-register, generally with a propellor hand. Case backs were engraved BREGUET MARINE NATIONALE AERONAUTIQUE NAVALE, together with an issue number. 500 pieces were ordered.

The watch on the right has an engraved bezel, but the caseback indicates that it was a BREGUET MARINE NATIONALE AERONAUTIQUE NAVALE model Issue Number 397. [7 ] Perhaps the case back was from another model and changed during repair or servicing, which was carried out centrally for the military.

Type 20 CEV 3 Register

This watch is the most complicated of all the French Military wristwatches: the " three register" Breguet chronograph was developed from the Navy model, with both 15 minutes and 12 hours registers, as well as a continuous auxiliary seconds. The mechanism was Valjoux 72/flyback, cal 225. An additional feature was the adjustable bezel graduated for 12 hours. 50 pieces were ordered.

Mathey – Tissot

Mathey-Tissot assembled the 5101/54 model for Breguet, and later produced both 2 and 3 register civilian models under their own name. The 2 register model is more prevalent. The subregister is 15 minutes.

The images below are representative of the Mathey – Tissot  civilian production and many similarities with the Bregeut Type 20 can be seen. Arrow head sweep second hand, baton hands with long thin pointers, propellor hand on 15 minute sub-register, broken into 3 minute sections.

The Starter

The starting point would be the model which started it all, the model 5101/54 for the French Airforce, with reeded dial and the wonderful onion crown.   The case back will be engraved 5101/54 and the dial will not be signed Breguet.   Although this is the most common Type 20  with military engraving,  expect to pay over $15,000 for a good model.   Other Type 20 models from Dodane, Auricoste, Airain and Vixa are less desirable, and cheaper. A Mathey-Tissot, almost identical, would be les than half price.

Case number 8113

The keeper

A rarer model is the BREGUET model engraved MARINE NATIONALE AERONAUTIQUE NAVALE on the rear case, of which only 500 were produced.   The model with the thin pointers at the end of the baton hands could easily cost $20,000 in good condition.

The grail

The grail is a brown faced 3 register CEV model, of which less than 50 were made. A price approaching $30,000 could be expected for a good model.
