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 metal bracelets and leather, rubber, nato, etc., it is possible to remove links, pierce/shorten with DIY tools, but only 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; wrist movement alone is not sufficient to maintain the required power reserve.
RULE FOR ALL WATCHES WITH DATE
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 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.)
