CONTENT

INFO
The photos were taken on the actual watch; please note that color may vary slightly due to reflections, shadows, or direct light during photographing.

IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, nato, etc., it is possible to remove links, drill/shorten with the proper tools; if you are not able to do it yourself, please consult a professional. All automatic watches, at first use, must be wound by hand in addition to wrist movement to achieve the necessary power reserve, as wrist movement alone is not sufficient.

GUIDELINE FOR ALL WATCHES WITH DATE
To avoid potential 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 adjustments, gently unscrew the crown counterclockwise. Remember to securely screw the crown back after adjusting desired settings.)
