Favre-Leuba FL 270 Watch Spare Parts: Detailed Overview for Collectors and Watchmakers
The Favre-Leuba FL 270 is a Swiss manual wind movement from the 1960s, recognized for its flat and delicate construction paired with robust power features. Featuring two mainspring barrels in parallel, it delivers a higher torque for improved power reserve and reliability. This 10.5 ligne calibre measures approximately 23.3 mm in diameter and 3.0 mm in height, running at 18,000 vibrations per hour (vph) with 17 synthetic jewels. Unlike typical flat movements, the FL 270 uses a central minute wheel coupled with a unique gear train design incorporating a riveted intermediate wheel, prized in vintage Favre-Leuba collections for precision and durability.
