This is a lovely example of a Universal Geneve Compax in 18kt yellow gold. The serial dates this Compax between 1943 to 1945. It features a yellow, sunburst-style nipple dial, and 3 registers, including an hour and minute counter.
The watch is in great vintage condition. The yellow gold case does not show signs of polishing. The dial is in nice condition, and has developed a light patina.
