Complete set (The box of the watch may differ from the photos depending on stock available 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 reflections of light, shadows or direct light during shooting.

IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, nato, etc., it is possible to remove links, punch/shorten with DIY tools, but only with the necessary tools; if you are not able to do it yourself, we kindly ask you to contact a professional.
All automatic watches on first use must also be wound from the crown; wrist movement 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 of watches have a screw-down crown; for settings you need to gently unscrew the crown counterclockwise. Don’t forget to securely close the crown after adjusting the desired settings.)
