INFO
The photos are taken of 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 straps, etc., it is possible to remove links, punch/shorten with the proper tools; if you are not able to do it yourself, please consult a professional. All automatic watches must be wound by the crown on first use—the motion of the wrist alone is not sufficient to maintain the required power reserve.
RULE FOR ALL WATCHES WITH DATE FUNCTION
To avoid potential damage to the movement, please do not set the date with the crown when the watch 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 you need to carefully unscrew the crown counterclockwise. Do not forget to firmly screw the crown back in after adjusting the desired settings.)
