An amazingly detailed post on how to buy a Seiko 6309 diver, one of the iconic Japanese divers of the last century. The 6309 has an automatic movement and is built like a tank with the crown at 4 o’clock. I have my father’s, which I redid completely after he left it sitting in a drawer for about 20 years. It’s a striking piece and, along with the Orange Monster, is a great newbie collector’s watch.
