For sale today is a super cool vintage Sicura skin-diver. Swiss-made, probably from ~1970's. This watch is running smoothly and keeping good time.

Case back is marked "auto-pression", not sure what that means. 19mm lugs set on a two-piece rubber strap with metal buckle. 17-jewel manual winding Swiss movement. Wind-ahead date display. Sicura watches are known for having a tenuous connection to Breitling. If I remember correctly, Sicura was once owned by the same guy that owned Breitling at the time. It's a bit of a stretch to connect the two brands, but I figured it was worth mentioning. I love the dial in this one! Very cool looking design. Asking $215 USD OBO including shipping within North America. Great international rates available too.
