INFO
The photos were taken on the actual watch; please note that color may show slight variations in shade due to reflections of light, shadows, or direct light during the photo shoot.

IMPORTANT NOTE FIRST USE
For all watches with metal bracelets and leather, rubber, nato, etc., it is possible to remove links, punch/shorten with the appropriate tools. If you are not able to do it yourself, please consult a professional. All automatic watches should be wound initially by the crown as wrist motion alone is not sufficient to maintain the required power reserve.

RULE FOR ALL WATCHES WITH DATE
To avoid possible damage to the mechanism, please 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 with the crown when the time is between 03:05 and 20:55. (Some models have a screw-down crown; for adjustments gently unscrew the crown counterclockwise. Remember to securely screw the crown back after making the desired adjustments.)
