We would like to introduce watches from Tressa, a Swiss watch manufacturer.

Tressa is a Swiss watch manufacturer that existed for just 20 years, starting in 1966.
This is a watch from a series called "Laser Beam" from around the 1970s, and is an automatic mechanical watch with a calendar.
It has a distinctive retro-futuristic design, and the machined alloy case has a heavy feel to it.
The overhaul history is unknown, but it is in good working order.

We hope this once-in-a-lifetime encounter will be a special one for you!
