universal geneve ultra thin vintage watch with rare double diamond setting

1960s vintage Universal Geneve formal ultra-thin dress watch, Cal 1-42 movement, 14k gold case, very rare double diamond setting at the 12 o’clock position, original Gemex band, ref. 40500, some patina on the dial, and it is in original unpolished condition. The unit was fully serviced and calibrated three years ago, and I rarely wear it, and it runs great. Nice watch. $2000 or best offer.
