This appears to be a vintage Anker mechanical wristwatch with a distinctive world-time rotating bezel. A few notable details: • Brand: “ANKER” • Movement marking: “17 RUBIS ANTICHOC” • “17 rubis” means 17 jewels in the movement. • “Antichoc” indicates shock protection. • Style: Likely a late 1960s to 1970s design. • Features: • Rotating city bezel with world cities (New York, Paris, Tokyo, etc.) • Internal 24-hour scale • Date window at 3 o’clock • Bold blue dial with oversized luminous markers • Case: Cushion-shaped chrome/plated case • Strap: Modern NATO-style replacement strap, not likely original. The watch has a strong “compressor/diver/world-time” aesthetic common in mid-century European watches. Anker was not a top luxury maker like Rolex or Omega, but many of these watches used solid Swiss mechanical movements and have become collectible for their styling. Condition observations from the photo: • Visible wear on the bezel and case plating • Crystal has scratches • Dial appears fairly well preserved • Hands and lume show aging/patina Depending on the exact movement inside and whether it runs properly, watches like this often sell in roughly: • $175–450USD in average working condition • More if recently serviced and fully original • Less if non-running or heavily worn
