INFO
The photos were taken on the actual watch; please note the color may vary slightly due to lighting reflections, shadows, or direct light during the shoot.
IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, nato straps, etc., it is possible to remove links, drill/shorten with DIY tools, but only with the necessary tools. If you’re not able to do it yourself, please consult a professional.
All automatic watches at first use must also wind from the crown; wrist movement alone is not enough to maintain the required power reserve.
RULE FOR ALL DATE DISPLAY 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; for setting, gently unscrew the crown counterclockwise. Don’t forget to securely reseal the crown after adjusting.)
