Very nice vintage wristwatch, it’s got a very worn but comfortable strap (that should probably be replaced) it ticks fairly nicely and lost about 15 minutes in one day (part of the charm of vintage watches and comes with the territory). It’s a very nice old piece and I’m sad to see it go but I’ve got too many so I’m reducing my collection.

This watch was manufactured by Braun & Zwahlen, a brand founded in 1905, during the war. The name "Fortress" is a fitting name for wartime, but after the war, Braun released many watches.
