I'm not usually one for picture posting, but thought I'd share these pics of a vintage SUB 300T I picked up about 4 years ago off Ebay. It's a Synchron era watch with a non-screw down crown, no HRV, but a Conquistador dial. No idea if the dial is original to the watch, but the hands have been relumed at some point, and at the time of purchase, the seller told me he had it serviced and pressure tested in 2004. Watch runs great. Anyways, enjoy.
