Great—this movement photo gives a lot more clarity. You’ve got a genuine vintage Omega automatic Ladymatic, and we can now narrow it down further: Movement details • “Adjusted Two (2) Positions” • “Twenty-Four 24 Jewels” • Automatic rotor signed “Omega Watch Co Swiss” This strongly points to an Omega caliber 66x series (most likely cal. 661 or 662), which were: • Introduced in the mid-to-late 1950s • Specifically designed for smaller women’s watches • Known for being high-quality micro-rotor-style automatics (very advanced for the time) What this means • Your watch is almost certainly from ~1955–1965 • It’s a legit, higher-grade Ladymatic, not an entry-level piece • The 24 jewels + adjustment indicates a better-spec movement Updated value estimate With this confirmed movement: • Running, unserviced: ~$300–$700 • Recently serviced, strong condition: ~$600–$1,000+ • If solid gold case (check for 14K/18K marks): can push $900–$1,500+ Important observations • The movement looks clean and complete, which is a big plus • The case interior (visible edge) suggests gold-plated, but you’ll need to check the inside case back for stamps like: • “14K” / “18K” (solid gold) • Or hallmarks / “gold cap” / “plaque” (plated) Overall This is a nice, collectible vintage Omega Ladymatic, not just a generic old watch. The movement alone confirms it’s a quality piece. Wach is perfect functional
