Universal Genève

A Universal Genève wristwatch combining calendar and chronograph displays. The Tri-Compax arrived in 1944 for the company's fiftieth anniversary and combines a chronograph with a full triple calendar and a moonphase. Continuous seconds sit at nine, a twelve hour register at six, a thirty minute register at three, and the date pointer with the moon at twelve. It ran through the 1940s to the 1960s across calibres 281, 287, and 481 in many sizes and metals.
