FERO Feldmann - Unknown - No reserve price - Men - 1970-1979

This appears to be a vintage world-time style wristwatch branded FERO Feldmann, marked “23 Jewels” and “10 ATM Tested”.

Notable details visible in the photo:
• Rotating bezel with world cities such as Sydney, London, Tokyo, Mexico, Chicago
• Dark blue dial and bezel with orange lettering
• Internal 24-hour/world-time scale
• Date window at about 3 o’clock showing “20”
• Tachymeter markings on the dial
• Cushion-shaped stainless steel case
• Likely from the 1970s era, based on the design language and typography

The watch looks inspired by the popular compressor/world-time dive watches of that period. FERO was a Swiss watch brand associated with mid-century mechanical watches rather than a major luxury manufacturer.
