FAQ

Quick answers about chronograph use, care tips, and service process.

Is the chronograph fully functional on this model?

Yes. The timing pushers operate the chronograph start/stop and reset functions, and the subdials respond accordingly under normal use.

How do I operate the chronograph correctly?

Use the upper pusher to start/stop timing. Use the lower pusher to reset only after the chronograph is stopped.

Avoid resetting while the chronograph is running to reduce internal stress.

Can I adjust the date quickly, and is there anything to avoid?

The date can be adjusted via the crown quickset position. For best practice, avoid quickset adjustments during late-night hours when the calendar mechanism may be engaged.

How should I care for the blue leather strap for long-term wear?

Keep the leather away from prolonged moisture and chemicals. Wipe gently with a soft cloth after wear. Store the watch in a dry place and avoid strong direct sunlight for extended periods.

Do you offer strap sizing or replacement options?

Yes. We can help confirm fit guidance and provide replacement strap options if you want a different color or material style.

What should I do if the watch arrives with a minor issue?

Contact support with your order number and clear photos/videos. We will troubleshoot step-by-step and arrange the best solution if service is needed.

Do you recommend a pressure test before water activities?

Yes. Shipping impact and temperature changes can affect sealing. A local pressure test is recommended before swimming or frequent water exposure.
