Hi guys, just got this Henri Sandoz vintage watch which looks kind of interesting, but don't know anything about it. Looks like 60s, but can't be 100% sure. What do you guys think? Also, looks like good quality, but the weird part is that I do own another Sandoz from the 70s, but on the movement, I don't see Henri Sandoz written on it, so wonder why this has Henri Sandoz on the movement, but only Sandoz on the dial. Any idea?
Here are some photos:
