Universal Geneve Tri-Compax 14K Gold Calibre UG 287
This Universal Genève Tri-Compax is in excellent condition. It has straight-line lugs and the oversized 36 mm 14k case has flat chronograph pushers and a snap-on case-back. The left side of the case features three pushers for changing the month, moon-phase and date functions.
The dial has a beautiful vintage patina, with Arabic numerals. The feuille hands mark the hours and the minutes, while the sub-dials and the chronograph movement has blue steel batons.
This complex watch has a thirty-minute register at three o’clock, a twelve-hour register at six o’clock and the sub-seconds register at nine o’clock. At noon, the dial features an aperture for the moon-phase and another sub-dial with stick hands to show the date.
On the left and right sides of it, apertures reveal the day and the month, respectively. The tachymeter graduation at the perimeter completes this truly stunning watch dial.
This vintage Tri-Compax is powered by the 17-jewel in-house Calibre 287, beating at a rate of 18,000 A/h. This movement has a Breguet hairspring and an outstanding column-wheel design. Based on the Calibre 285, its production started in 1944. This iconic base movement was created by Martel, and by using its variable diameter technology, the Calibre 287 came in a 33.2 mm (15 lignes) size, with a mere 6.05 mm thickness. Like the other movements belonging to this prestigious family of movements, it was also shared with Zenith (Calibre 156). With Universal Genève being the first maker of a wristwatch with two chronograph pushers, this stunning piece comes with an extract of archive from UG, dating it to 1945.
As a vintage watch, we cannot warranty its current water resistance.
