Description: Rolex Oysterdate 6694 Pre-owned Rolex Oysterdate ref 6694 (1963) is about as straightforward as vintage Rolex gets, and that’s part of the appeal. At a glance, it looks a lot like a Datejust from the same era, but there’s one big difference. The Datejust has a self-winding “Perpetual” Movement, and the OysterDate is a manual-wind watch, so it needs a quick wind every day or so to keep it running. A little more interaction, which some people actually prefer. Ref.
