CONTENT
Full set (The watch box may differ from the photos depending on stock available in the warehouse at the time of shipment, but we guarantee the original box of the brand)
INFO
The photos were truly taken on the watch; please note that colors may vary slightly in shade due to reflections of light, shadows, or direct light on the watch during shooting.
IMPORTANT NOTE FIRST USE
For all watches with steel bracelets and leather, rubber, nato, etc., it is possible to remove links, pierce/shorten with DIY tools; but only with the necessary tools. If you are not able to do it yourself, please kindly contact a professional.
All automatic watches at first use must be wound from the crown as well; simply wrist movement is not enough to maintain the required power reserve.
RULE FOR ALL WATCHES WITH A DATE
To avoid possible damage to the movement, please do not set the date using the crown when the time on the watch is between 21:00 and 3:00. 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 changing the desired settings.)
