INFO
The photos were taken on the actual watch; please note that color may vary slightly due to light 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, punch/shorten with the necessary tools. If you are not able to do it yourself, please consult a professional. All automatic watches require winding at first use; wrist movement alone is not sufficient to maintain the necessary power reserve.
RULE FOR ALL WATCHES WITH DATE
To avoid possible damage to the mechanism, please do not set the date via the crown when the time is between 21:00 and 03:00. It is advisable to set the date 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 securely screw the crown back after making the desired adjustments.)
