Men's watch with black waffle dial, Arabic numerals at 3,6,9 &12, and sword indices. Dial marked waterproof. M1 (1961) 17 jewel 11 AFC movement. I just managed to get the back open (used superglue and a socket). It looks like the stem may be there but there is no crown. Runs in dial down, stops in dial up. I suspect it's possibly a pivot. Casual research suggests to me that it is a Seabee 'B', although it has a different case than I've seen on others.
This watch should clean up nicely. As it is running dial down, hopefully it won't need a whole lot to bring it back. If I don't find any interested parties here, I'll probably put it up on eBay. I'm downsizing so, there will be others there, too. I've got 4 caliber 214s (all recently serviced), a couple Squadron Bs, as well as others. Let me know if interested. Thanks.
