The Jaeger Chronograph Ref. 224115 represents one of the most fascinating collaborations in Swiss watchmaking history. Produced in the 1940s, this chronograph combines Jaeger’s prestige with Universal Genève’s legendary Calibre 285, a column-wheel movement celebrated for its precision and reliability. Universal Genève was widely regarded at the time as the chronograph specialist, supplying movements not only for its own models but also for a handful of prestigious maisons. These chronographs were effectively “white label” creations, where Jaeger relied on UG’s world-class expertise, resulting in pieces that are today highly prized for their rarity and historical importance.

A Word on Condition
This watch remains in very good condition for a 1940s chronograph, retaining its original Jaeger-signed dial with even ageing. The case shows honest wear consistent with its age, preserving the sharp lines that distinguish UG-powered Jaeger chronographs.
Universal Genève vs Valjoux Jaeger Chronographs
During the 1940s, Jaeger produced chronographs powered by both Universal Genève and Valjoux movements. The Universal Genève Cal. 285 versions, such as this Ref. 224115, are far rarer and considered technically superior thanks to the smoothness and reliability of the column-wheel design. Valjoux-powered Jaeger chronographs were produced in greater numbers, making UG-powered examples highly desirable among collectors today. This distinction places the 224115 in a different league, combining scarcity with horological significance.
Why Buy This Watch
Collectors recognise the rarity and importance of the Jaeger Chronograph Ref. 224115. With only a limited number produced and powered by the Universal Genève Cal. 285, this piece is a tangible link to a unique era when Jaeger entrusted its chronographs to the acknowledged masters of the complication. The result is a highly collectible watch that embodies the best of two legendary brands. For enthusiasts of vintage chronographs, this Jaeger is an outstanding and historically significant acquisition.
