How do I ensure the watch remains water-resistant?

Troubleshooting

Watch stopped running after not being worn for a few days

The watch has a 72-hour power reserve. If it has been stationary for longer, manually wind the crown 20-30 times to replenish the mainspring.

Date is changing at noon instead of midnight

The movement is set 12 hours out of sync. Advance the time by 12 hours to correct the AM/PM cycle.

Difficulty adjusting the bracelet length

Ensure you are utilizing the micro-adjustment settings inside the folding clasp before attempting to remove permanent steel links.

Setup, Compatibility & Care

To set the time and date, unscrew the crown counter-clockwise until it pops out to the manual winding position. Pull the crown to the first click to adjust the date, and the second click to adjust the time. Always ensure the crown is pushed back in and screwed down tightly before exposing the watch to water to maintain its seal. The stainless steel bracelet can be adjusted via the links and the micro-adjustment settings on the clasp. For cleaning, use fresh water and a mild soap to remove salt or sweat buildup, then dry with a soft cloth. Avoid using harsh chemicals or ultrasonic cleaners which may damage the anti-reflective coating on the crystal.
