INFO
The photos were taken on the actual watch; please note color may vary slightly due to lighting reflections, shadows, or direct light during shooting.
IMPORTANT NOTE FOR FIRST USE
For all watches with stainless steel bracelets and leather, rubber, NATO, etc., it is possible to remove links, and adjust size with the proper tools. If you are not able to do it yourself, please seek a professional.
All automatic watches require winding from the crown at first use; wrist movement alone is not enough to maintain the required power reserve.
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 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. Do not forget to reseal the crown properly after changing the settings.)
