Interesting stainless one piece waterproof case that opens from the front. I haven't attempted to open it to view the movement but assume it's 17J. Judging by the lack of any opening marks on the bezel ring, I am assuming this one has never been opened. Case back is dated M2. Super clean and displaying understated 60's elegance....
This one is a bit of a puzzle. Number 12 with all other indices being sticks. The 3, 6 and 9 appear just slightly bigger than the rest. Dial has a subtle hourglass shadow with lume dots; marked "Selfwinding". The combination of Selfwinding front loading waterproof with a distinctive dial would seem to be an easy ID, but I've been unable to track this one down. This was another "what the heck is that" purchase.
Watch appears to have seen little wear. Came to me without a band and is currently keeping perfect time.
