Positioning of the Winding Crown
Four positions of the winding crown
The winding crown on a Rolex GMT-Master II watch has four positions: 0, 1, 2, and 3. These positions play a crucial role in operating various functions of the watch. Position 0, also known as the neutral position, is used for normal wear and keeping the watch movement running. Positions 1, 2, and 3 are utilized for manually winding the movement, setting the time and date, and adjusting additional functions.
Importance of keeping the crown at position zero
Keeping the winding crown at position zero when the watch is not being adjusted or wound is essential for several reasons.

It is important to note that overwinding the watch can damage the movement. Once the watch is fully wound, the crown should be pushed back in and screwed tightly to ensure the watch remains water-resistant.
Frequency of winding the crown for maintenance
The frequency of winding the crown for maintenance purposes depends on the individual’s wearing habits and the specific model of the Rolex GMT-Master II. Generally, it is recommended to manually wind the watch every day or every other day to ensure optimum performance.
However, if the watch is worn consistently, the natural movements of the wearer’s wrist will automatically wind the watch, eliminating the need for manual winding. It is advisable to consult the specific user manual or seek advice from a trusted watch technician to determine the appropriate winding frequency for your Rolex GMT-Master II based on your personal usage.
