Universal Genève’s Tri-Compax wristwatch was released in 1944 as a celebration of the firms 15th anniversary, as well as a successor to their first release of the iconic Aero-Compax introduced in 1936. Today, vintage wristwatches by the firm are highly sought after for their modern mid-century aesthetics and superb quality with offerings such as the Uni-Compax, the famed Polerouter designed by young Gerald Genta, and last but not least the present model, the Tri-Compax referring to the three featured complications; chronograph, calendar and moon phases.

The present Tri-Compax ref. 522101-1 was produced during circa 1961, by the reference number one can decipher details about the reference such as first digit referring to the case metal (5 for 14K yellow gold), the second digit for the type of movement (2 for chronograph) and the third digit for the size of the base plate (2 for cal. 281).

Preserved in a remarkably well-preserved condition with a strong case and crisp edges, the watch has furthermore gained a beautiful warm patina of the yellow gold case and a pleasingly aged creamy dial. This is a particularly fine example of a watch with a long and distinguished history, and fitting for all collectors who appreciate the horological past.
