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

INFO
The photos were taken on the watch itself; 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 metal bracelets and leather, rubber, NATO, etc., it is possible to remove links, punch/shorten with the proper tools; if you are not able to do it yourself, please consult a professional.
All automatic watches on first use must be wound by the crown as wrist movement alone is not enough to maintain the required power reserve.

RULE FOR ALL WATCHES WITH DATE
To avoid possible damage to the movement, please do not set the date from 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 you need to gently unscrew the crown counterclockwise. Remember to securely screw the crown back after modifying the settings.)
