Re: Rolex oyster perpetual datejust time/date setting... Depending on how old the watch is, It may be quick set or older models are not quick set. In older models you need to unscrew the crown, pull out the crown and rotate the crown to set the time, and in order to set the date rotate the hour hand past 12 twice in order for the date to change.
Modern Rolexes have perpetual (automatic) movements, meaning the watch is powered by the movement of your wrist. When you move your wrist, the rotor winds the watch. Vintage caliber 3035 movement. If you wear your watch daily, the rotor should do a sufficient job of winding the movement.In the event you donât wear your automatic watch daily, itâs important that you manually wind your watch for it to keep accurate time. Winding your watch is an easy process.f your Rolex is still losing significant time after winding it, take it to an authorized Rolex service center. A watchmaker can tell you whatâs wrong with it and possibly save you major money by conducting the repair on-site before you ship it off to Rolex for hundreds (or thousands) of dollars.
