Yema 15 jewels Watch 240685 Good Working Condition Gold plated Dates from the 1950s to early 1960s. Case diameter: 33mm Lug Width: 17mm Lug-to-Lug: 40mm This timepiece is a classic example of mid-century French watchmaking from Yema, a brand founded in 1948 in Besançon, France. While Yema is famous today for its "Superman" divers and "Rallygraf" chronographs, this model represents their elegant dress watch era from the 1950s to early 1960s. • Brand: Yema (Besançon, France). • Jewels: 15 Jewels (a standard count for quality manual-wind movements of this era). • Movement: Based on the internal photos, this appears to be a French-made Cupillard or Jeambrun ebauche (likely a Cupillard 233 variant). These were the "workhorse" movements of the French watch industry, known for their reliability and ease of service. • Dial Features: * Sub-seconds: The small dial at the 6 o'clock position tracks seconds independently of the main hands. • Antimagnetic: Indicated on the dial, a common marketing feature at the time highlighting the watch's resistance to magnetic fields. • Case: Marked "Stainless Steel Back," "Antimagnetic,", Gold plated and "Waterprotected." The serial/reference number 240685 is visible. In vintage Yema watches, these numbers often functioned as internal reference codes for service parts
