Complete set (The watch box may differ from the photos depending on available stock at the time of shipment, but we guarantee the original brand box)

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

IMPORTANT NOTE FIRST USE
For all watches with steel bracelets and leather, rubber, NATO straps, etc., it is possible to remove links, drill/shorten with a DIY method, but only with the necessary tools. If you’re not able to do it yourself, please consult a professional.
All automatic watches must be wound at first use, also via crown; the motion of the wrist alone is not sufficient to maintain the necessary 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 it is necessary to unscrew the crown gently counterclockwise. Do not forget to screw the crown back tightly after changing the desired settings.)
