FAQ

1. What if there is water inside the watch?
A small amount of condensation will typically dissipate on its own. Wearing the watch face-down for a couple of hours can help accelerate this. If actual water droplets are visible inside, please have the watch serviced promptly.

2. How does automatic winding work?
The watch winds itself through the natural movement of your wrist. Wearing it for 8+ hours daily ensures optimal timekeeping. You can also manually wind it by rotating the crown clockwise (without pulling it out) approximately 15 turns.

3. Calendar adjustment warning:
Avoid adjusting the date or day between 8:00 PM and 4:00 AM, as the calendar mechanism is mid-cycle during this period and may be damaged. Keep the watch away from strong magnetic fields (TVs, computers) to maintain accuracy.
