INFO
The photos were taken on the actual watch; please note that color may vary slightly due to light reflections, shadows, or direct lighting during shooting.
IMPORTANT NOTE BEFORE FIRST USE
For all watches with metal bracelets and leather, rubber, nato straps, etc., it is possible to remove links, pierce/shorten with the proper tools; if you are not able to do it yourself, please consult a professional. All automatic watches must be wound for the first use; wrist movement alone is not enough to maintain the required power reserve.
RULE FOR ALL WATCHES WITH A DATE FUNCTION
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 advisable 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 securely screw the crown back after adjusting the desired settings.)
