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, pierce/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 must be wound at first use; relying on wrist movement alone is not sufficient to maintain the required power reserve.
RULE FOR ALL WATCHES WITH DATE FUNCTION
To avoid potential 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 settings, gently unscrew the crown counterclockwise. Remember to reseal the crown properly after adjusting.)
