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, and adjust size with the necessary tools. If you are not able to do it yourself, please consult a professional.
All automatic watches must be wound at first use even if worn on the wrist to reach the required power reserve; wrist movement alone is not enough.
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 03:00. It is recommended to set the date 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 desired settings.)
