What is the power reserve?

Is the crystal truly scratch-resistant?

What is the lug width for strap changes?

Troubleshooting

The watch stopped running

The power reserve has likely depleted. Manually wind the crown 20-30 times or wear the watch to allow the rotor to build up tension.

The watch is gaining or losing time

Mechanical watches can be affected by temperature and positional changes. If it is significantly inaccurate, it may require professional regulation.

The bracelet is too loose

Take the watch to a certified watchmaker to have individual links removed from the stainless steel bracelet for a perfect fit.

Setup, Compatibility & Care

To set the time, pull the crown out to the second click and rotate it clockwise or counter-clockwise until the hands reach the correct position, then push the crown back in. To manually wind the movement, ensure the crown is pushed all the way in and rotate it approximately 20-30 times.

For care, rinse the stainless steel case and bracelet with fresh water after exposure to saltwater or sweat to prevent grime buildup in the links. Use a soft, lint-free cloth to buff the sapphire crystal and mirror-polished links. Store the watch away from strong magnetic fields—such as large speakers or induction cooktops—to ensure the hairspring remains accurate.
