Binatime Seawatch
You see quite a lot of watches in this style with the square shouldered case. I've seen them with various different names on the dial. Not really a divers watch by today's standards at 60 metres. Note the T marks at 3,6 and 9 minutes past. Most likely for timing phone calls when they used to charge by 3 minute blocks. Has a very plain looking EB 8021N cal. 23 Jewel movement.
