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 stainless steel bracelets and leather, rubber, NATO straps, etc., it is possible to remove links, punch/shorten using the proper tools. If you are not able to do this yourself, please consult a professional. All automatic watches must be wound initially from the crown as wrist movement alone is not sufficient to maintain the necessary power reserve.
RULE FOR ALL WATCHES WITH DATE
To avoid potential damage to the movement, please do not set the date using the crown when the time is between 21:00 and 03:00. It is recommended 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. Remember to securely screw the crown back after adjusting.)
