INFO
The photos are 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., it is possible to remove links, drill/shorten with the proper tools. If you are not able to do it yourself, please consult a professional.
All automatic watches require the movement to be wound at first use; simply wearing the watch is not enough to fully wind the mainspring.

To avoid potential damage to the movement, please do not set the date with the crown when the time is between 21:00 and 03:00. It is advisable to set the date with the crown when the time is between 03:05 and 20:55. (Some models have a screw-down crown; for settings, gently unscrew the crown counterclockwise. Do not forget to securely close the crown after adjusting.)
