INFO
The photos were taken on the actual watch; please note that color may vary slightly due to reflections of light, shadows, or direct light on the watch during photography.
IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, Nato, etc., it is possible to remove links, pierce/shorten 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 even with wrist movement, as the motion 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 you may need to unscrew the crown gently counterclockwise. Don’t forget to securely screw the crown back after adjusting.)
