advertisment My chronology ends here because that's the end of my intense interest in the company. They do several beautiful skeletonized wristwatches, but the very early Tri-Compax is the object of my affection. (You will see an 1960s model, but only to demonstrate why I focus on the earlier ones :-)

moon

The Tri-Compax is a tripledate moonphase chronograph. It's the moonphase dial that's the most distinctive part of the Tri-Compax face. The disc therein, sporting a painted facsimile of the moon, makes one revolution each 29 days; a lunar month.

What could be more attractive and powerful than having the entire cosmos on one's wrist?

The Tri-Compax has a 17-jewel signed manual wind calendar/chronograph movement (cal. 287), round snap back case (the watch comes in a variety of widths), a satin painted numeral dial, and four registers; constant seconds, 30-minute and 12-hour recorders, date, apertures for month, day, and phases of the moon, chronograph sweep seconds, dial calibrated for tachymetre.

Here are some variants on the Tri-Compax:


Stainless Steel, English

Stainless Steel, luminescent hands

Stainless Steel, Spanish

Black face, Spanish

Pink Gold, Thai

18 K, Thai
