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 brand box)
INFO
The photos are taken on the actual watch. Please note that color may vary slightly due to lighting reflections, 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, pierce/shorten with the provided tools. If you are not confident doing it yourself, please consult a professional.
All automatic watches need to be wound initially via the crown as wrist motion alone is not enough to maintain the required power reserve.
RULE FOR ALL WATCHES WITH DATE
To avoid potential damage to the watch mechanism, please do not set the date via the crown when the time is between 21:00 and 03:00. It is recommended to set the date when the time is between 03:05 and 20:55. (Some models have a screw-down crown; to adjust settings, gently unscrew the crown counterclockwise. Remember to securely screw the crown back after completing the desired settings.)
