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.
Setting the Time. The time on this watch is set by changing the digital display time then transferring the digital time to the hands. 1 - Turn the crown until the mode hand points to the time mode [TME]. 2 - Press either button (A) or (B) to select the city for which the time is to be set.
