I have on a Trias automatic watch today (German). Look similar to yours. I've had it on my winder for about a month now so I said I better wear it. I've been wearing my Citizen Eco-Drive Nighthawk BJ7000-52E for a while now. I have like 20 watches and I'm very bad about changing watches. I got the Trias on e-bay a few years ago. It had a cheap strap that I think wasn't leather. I changed it for a black leather strap with white stitch and a deployant clasp. Now it's useable. By the way, nice watch you got there.
