I haven’t worn this one for, well, since when, I don’t remember. I put it on this morning and I was reminded why I hadn’t worn it! The Tissot stainless steel bracelet is about as uncomfortable as a bracelet can be! But I really prefer a watch with a calendar, and the 61 year old Accutron 214 I was wearing, didn’t have the date. My best guess is that this Tissot PR516 self-winder is from circa 1965 or so. I see I need to do a bit of “dusting” behind the crystal!
