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

INFO
The photos are taken of the watch; please note that color may show slight variations in shade due to reflections of light, shadows, or direct light on the watch during shooting.

IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, nato straps, 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, please kindly consult a professional.
All automatic watches on first use should also be wound from the crown, as wrist movement alone is not sufficient 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 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, gently unscrew the crown counterclockwise. Don’t forget to securely screw the crown back after adjusting.)
