With the popularity of mechanical watches, you’ve probably heard the term “power reserve.” But what does power reserve really mean? power reserve indicates the amount of time the movement can dispense constant energy (the autonomy) before the watch needs to be wound. Mechanical watches are the kind of watches you need to wind up manually everyday or almost everyday. Some of them have a power reserve of 2-3 days (48-72 hours), some of them a solid week/7 days of power reserve. Some of these mechanical watches have a “power reserve display” on their dials which tells you when you need to manually wind up the watch again before it stops. However, most mechanical watches don’t have a power reserve display on their dials. It’s recommended that you wind them up manually every day or every second day.

Rolex watches require a certain amount of reserve power in order for the movement to operate properly. When your Rolex has been serviced and returned it is necessary to manually wind the movement. You will need to un-screw the crown. The first position is the winding position. From this position, wind your Rolex 40 full turns of the crown. When winding is completed, screw the crown down to its original position. Your Rolex will now have the correct amount of reserve power to properly operate the movement. From this point on, depending upon your activity level, your Rolex should wind automatically maintaining the correct amount of power.
