INFO
The photos were 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 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 on first use must also be wound by the crown; wrist movement alone is not sufficient to maintain the required power reserve.
REGULATION FOR ALL DATE-FUNCTION WATCHES
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 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; to adjust, gently unscrew the crown counterclockwise. Remember to fully screw the crown back in after making the desired adjustments.
