A Rose Gold Chronograph Icon with Jumbo Presence - Universal Genève Tri-Compax Ref. 12268 Jumbo Rose

The Universal Genève Tri-Compax is one of the most iconic and collectible vintage chronographs ever made — and this ref. 12268 from the 1950s is a particularly rare and desirable version.

Housed in a jumbo-sized 37 mm 18k rose gold case with sharp angled lugs, this piece has the perfect proportions for modern wrists while retaining every bit of vintage charm. The cream dial, untouched and evenly patinated over time, displays a full triple calendar with moonphase and chronograph layout — one of the most beloved configurations in vintage watch collecting.

A detail that sets this piece apart is the “H.P.C.” dial marking, believed to stand for “High Precision Chronometer” — a rare designation only found on select UG models and highly sought after by connoisseurs.

Powered by the revered Caliber 481, this Tri-Compax blends technical complexity with elegant 1950s aesthetics — a grail-worthy piece of Swiss horological history.
