Ch. Oudin Split-Seconds Chronograph Pocket Watch

Partially verified

This open-face keyless-winding pocket watch signed by Ch. Oudin, Paris, is dated circa 1910 by the source. The timepiece is housed in a 51 mm nickel-plated metal case and is powered by an 18-ligne caliber movement with a lever escapement. Its white enamel dial features painted Arabic numerals, an outer chronograph track, a 30-minute register at 12 o'clock, and continuous subsidiary seconds at 6 o'clock. The split-seconds complication is operated via an olive-shaped push-piece located on the case band near 11 o'clock, alongside crown-activated chronograph functions.
