INFO
The photos were taken on the actual watch; please note that color may vary slightly due to lighting reflections, shadows, or direct light during shooting.

IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, nato, etc., links can be removed, and the strap can be shortened with the proper tools. If you’re not able to do this yourself, please consult a professional.
All automatic watches must be wound initially via the crown; merely moving the wrist is not enough to maintain the required power reserve.

RULE FOR ALL WATCHES WITH DATE
To avoid potential damage to the movement, do not set the date with the crown when the time is between 21:00 and 03:00. It is recommended to set the date when the time is between 03:05 and 20:55. (Some models have a screw-down crown; for settings, gently unscrew the crown counterclockwise. Don’t forget to securely screw the crown back in after adjusting.)
