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.
1 On the right side of you're chronograph watch pull out the dial in the center located on the face of the watch until it stops at the first extended position. 2  To set the current time, turn the dial to rotate the hour, minute and second hand until it reaches the right time.
