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, poke/shorten with the right tools; if you are not able to do it yourself, kindly seek a professional.
All automatic watches must be charged on first use by turning the crown; wrist movement alone is not sufficient to maintain the necessary 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 with the crown when the time is between 03:05 and 20:55 (Some models have a screw-down crown; for settings you may need to unscrew the crown gently counterclockwise. Remember to screw the crown back in firmly after adjusting desired settings.)
