1950s Vintage Mundial Chronograph – Lemania 1270 (CH27 Family)
History & Movement
This Mundial chronograph dates to the early 1950s and is powered by the Lemania Caliber 1270, part of the CH27 movement family that later evolved into the Omega 320 and 321 series. The 1270 is a manual-wind, cam-switched chronograph with 17 jewels and an 18,000 vph beat rate, produced during a short window beginning around 1950.
Lemania supplied this movement to several Swiss manufacturers, including private-label brands such as Mundial, Herodia, and Chronographe Suisse. These early post-war chronographs are appreciated for their thin cases, elegant dial designs, and the reliability of Lemania’s engineering. Surviving examples in clean working condition have become increasingly collectible due to the movement’s direct lineage to some of the most iconic mid-century chronographs.
Description
This is a beautiful example of a 1950s Mundial chronograph powered by the Lemania 1270. The watch is running great and keeping time. The chronograph functions properly, though the start pusher requires a firmer press to engage — a common characteristic of early Lemania cam-switched movements.
The dial retains its vintage charm with lots of patina and coloration, with some print fading. The size of the watch presents well on the wrist. Please review all photos carefully, as they are part of the description. A strong addition for collectors of early Lemania-powered chronographs.
