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 brand box)
INFO
The photos are taken on the watch itself; please note that color may vary slightly due to light reflections, shadows, or direct light 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, perforate/shorten with DIY tools, but only with the necessary tools. If you are not able to do it yourself, please seek a professional.
All automatic watches need to be wound at first use by turning the crown; wrist movement alone is not sufficient to maintain the required power reserve.
RULE FOR ALL WATCHES WITH DATE
To avoid potential 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 when the time is between 03:05 and 20:55. (Some models have a screw-down crown; for settings, gently unscrew the crown counterclockwise. Remember to securely screw the crown back after adjusting.)
