In 1944 the tri-compax was launched. Right away the sales of Universal increased all over the world. Universal became a synonym for quality, good taste and reliability. This piece was and still is considered a masterpiece; featuring full calendar, moon phase and of course the chronograph. In the earliest models, we typically see the use of the Cal. 287, which was replaced in the late 1940’s by the Cal. 481. This caliber would yet again be changed in the 1950’s for the even more compact Cal.281.
The Tri-Compax’s complex dial is perfectly laid out in a very clean and organised fashion. There are many case variations known from 33mm to an oversized 38mm, either in steel or gold. Among tri-compax wearers: President Truman. He wore it at the Postdam Conference in 1945, if its good enough to wear whilst negotiating the end of World War 2, then it’s good enough for any occasion.
