This circa 1945 Universal Geneve Tri-Compax measures 34.5mm. with square pushers and is in ultra-clean condition. The dial on this watch has been expertly restored and really does look fantastic. This watch has many functions including hours, minutes, seconds, day, date, month, moon phase, 30 minute counter, and 12 hour counter which all function as they should, as the watch was recently serviced. It is very important to always start the chrono function with the top button and stop it with the top button. Only use the bottom button to reset the chrono hand to 12, never to stop the chrono function. Never set any of the functions such as the, day, date, month, etc. between the hours of 9pm to 2am to avoid damaging the movement. Please note all the blued steel hands are original to this watch. This is a spectacular example! $3450.
