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 actual shots of the watch. 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, etc., links can be removed, and the band can be shortened using the proper tools. If you are not able to do it yourself, please seek a professional.
All automatic watches require charging from the crown at first use; wrist movement alone is not sufficient to maintain the necessary 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. Do not forget to reseal the crown properly after modifying the desired settings.)
