Thank you! It's my second, and they came in different sizes with different movements. It was a successful model line, and for good reasons. The screw-back cases were very good, the movements both excellent and aesthetically pleasing, and the dials often attractive. Below you'll see (first) the movement on this watch (33mm excluding crown), and my earlier one (35mm). In fact, I like the cal. 81 in my earlier one so much that I had a nice display back made for it!
In summary, they are excellent and underrated (and valued) watches.
Cheers,
Tony C.
