Universal Geneve Bumper Polarouter


The aircrew who flew Helge Viking on the first commercial SAS Douglas DC-6B flight over the pole from Copenhagen to Los Angeles on November 15, 1954 were each presented with a commemorative Universal Geneve Polarouter watch in 1954 (Ref 1).

At the same time the Leif Viking took off from Los Angeles and carried out the reverse journey, with the planes passing one another near the North Pole.  

Commemorative letters were posted to celebrate the occasion, post marking the cities where the planes landed on the journey.

Also, at the same time, Carlsberg also produced a commemorative Polar Beer.  The beer label is rare, and harder to find than the Polarouter watch, but one recently sold to a collector for USD 2.  The watch is much more sought after, and more valuable.

SAS had been experimenting with a polar route since November 1952, and needed to develop reliable navigational aids capable of operating near the North Pole, including antimagnetic chronographs.   Universal Geneve collaborated with SAS, and the Polarouter watch was developed in this period, some models of which were certified as chronometres.

This article deals with the initial calibre 138SS Polarouter, which was the forerunner of many models of Polerouter watches.

The Polarouter

The Polarouter was partly designed by Gerald Genta at the age of 23.  It is reminiscent of the Grand Seiko with double curved lugs, and the images in this article show the classic lines of the model.

It was powered by the caliber 138 SS movement.

The movement used in the early Polarouter and Polerouter models was the caliber 138 SS. It was introduced by Universal Genève in 1948, first as caliber 138 with a subsidiary second and then with a central second as caliber 138 SS.  The caliber 138 SS measures 28.2 mm in diameter and 5.55 mm in thickness. Its balance makes 18,000 vibrations per hour. The self-winding weight oscillates 315 degrees between two springs acting as shock absorbers, the so-called bumpers. This mechanism only winds the mainspring during one motion, and this inefficiency meant the watch often needed hand winding. The caliber 138 SS has 17 jewels, a plain surface finish and is rhodium-plated. It is shock-proof and anti-magnetic. Despite the precision and reliability that was proven on duty for SAS, the movement was replaced by the Microtor movement after approximately one year of production, as this was a more efficient movement.  

For an article on servicing the caliber 138SS see ref 2.

The name changed to Polerouter after a few months, and at the same time the screw in case back opening mechanism changed from 6 keys to a dodecagon.

The watch is 50m waterproof. The waterproof construction is achieved by a tension ring, and the tension ring variations are a feature of the many dial combinations.

The Polerouter was assembled in a case with a screw back, with the movement, the curved dial, the tension ring, and the crystal.   There was plenty of opportunity to vary the combinations of dials and bezels.   There were also three case types, stainless steel, 300 micron 18k gold cap, and 18k gold.

The dials came with or without cross hairs, and with or without chapter rings.   The chapter rings were ticks, dots, or dots with lume at the 5 minute markers.  The bezels had raised indexes at the 5 minute markers, and were plain metal, fluted between the indexes, or with fluted indexes, or coloured with bakelite applied between the indexes.   The hands were folded Dauphine, fluted Dauphine, Dauphine with triangular lumed inserts, or broad arrow.

Consequently, either during official production, or unofficial production, or in a watchmakers studio, the number of actual case, dial, hand and bezel combinations was huge.

The advertisement below shows some of the range of Polarouters.

The Stainless Steel cased Polarouters were the 20217 series, the 300 micron gold capped the 20214 series and the gold models the 10234 series, the 10234 models using different lugs on the case.

Polarouter 20217-1

The first model was 20217-1, released in 1954.

The 20217 series were in stainless steel cases.

This dial is black, with cross hairs, and no chapter ring.  The tension ring has raised broad index markers, with radial fluting between.  The crown is either signed U, or unsigned.

The movement was the Caliber 138SS, the so called bumper model.   The bumper weight can be seen below between the two springs, and this can rotate about 315 degrees.

The case back was a screw back with 6 keys, with the Universal Geneve logo, WATERPROOF, serial number, and model number 20717-1

Below is model 10234 1TL,  produced in 1958.  This is a rare model with a gold bracelet in shape of a belt with buckle (special patent).  This has a solid case, polished, screwed-down case back, and straight concave lugs.  Two-tone pink gold in two parts (special patent) bearing the effigy of King Faysal of Saudi Arabia, with fluted indexes on a polished outer ring.  Dauphine pink gold hands. 

In April 1958, the Minister of Finance of Saudi Arabia, Mr. Srurl El Sabban, visited the Universal 
Genève stand at the "Foire de Bâle" and subsequently ordered approximately 50 examples of this watch bearing the effigy of King Faysal. This model represents Universal Genève's most advanced technology at the time, embodying 3 patented innovations.

The Polerouter with the 138SS bumper movement was only produced for about 1 year. Hence the models are relatively rare, as about 2500 units only were produced.  In addition to the relationship with SAS, some customised production for other clients was also carried out.  Bearing this in mind we have the following recommendations.

The Beater

Almost any of the Gerald Genta influenced watches are desirable, but perhaps something with Polarouter on the dial indicates the early intent of this watch.  The early Polarouters often have narrow indices on the tension ring away from the cross hairs.


The Keeper

A broad arrow version would be the keeper.   These are rare and currently fetch several thousand dollars.   Below is a later version with lume on the hands but radial fluting on the tension ring.

Polerouter broad arrow

The Grail

Although not a Gerald Genta influenced design, the grail would be the gold SAS Polarouter issued as a commemorative piece for the SAS commencement flight from Copenhagen to and from Los Angeles.   This is close to a unique watch, and the price would be USD 10,000 plus.
