INFO
The photos are taken on the actual watch; please note that color may vary slightly due to light 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, punch/shorten with the proper tools; if you are not able to do it yourself, please consult a professional. All automatic watches at first use must be wound via the crown as wrist movement alone is not sufficient to maintain the required power reserve.
RULE FOR ALL WATCHES WITH DATE
To avoid possible damage to the movement, please do not set the date with the crown when the time is between 21:00 and 3:00. 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. Do not forget to securely screw the crown back after adjusting.)
