INFO
The photos were taken directly on the watch; please note that color may slightly vary 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 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 charging from the crown on first use; the 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 you may need to unscrew the crown gently counterclockwise. Don’t forget to securely screw the crown back in after modifying the desired settings.)
