Q. Is the anyway that I can self regulate my Rolex?
A. Yes you can self regulate your Rolex. The following information is from Rolex. It is interesting and might help correct for a few seconds of error in your watches timekeeping ability.
If your watch loses or gains a few seconds per day (remember there are 86,400 seconds in 24 hours!), you can correct it without expert aid. The rate of a watch varies slightly depending upon its position. Take it off at night and place it as follows:
1. To gain a few seconds: Lay the watch flat with the dial uppermost.
2. To lose a few seconds: Lay the watch vertically with the winding-button downwards.
3. To lose rather more seconds: Lay the watch vertically with the winding-button uppermost.
Q. Do I need to wind my Rolex even though it is an automatic winding watch?
A. If you have just received your Rolex back from having it serviced or if you have just purchased a new Rolex you will have to wind the watch manually in order to supply your Rolex with the correct amount of reserve power. Here's how to do it. Unscrew the crown. From this position, wind the watch at least 40 full turns of the crown. Set the watch to the correct time. When this is completed, push the crown back in and screw it all the way down. This should supply your Rolex with plenty of reserve power to keep it running. If you are an inactive person, it may be necessary to wind your watch upon occasion in order to keep it running.
