I've never wanted to own a dive watch until recently, and now, for no reason I can understand, I want one. But - I want a cheap mechanical or automatic watch. I'm thinking along the lines of something like an Orient Mako II, or maybe a Vostok Amphibia. I'd prefer an older established brand than a new microbrand - although I understand there are some absolutely terrific microbrand dive watches. In my own home town, the Melbourne Watch Company's "Sorrento" is one such - although more expensive than I want to spend right now. I have no problem with a pre-owned watch.
But maybe the experts on this forum have better ideas for me?
