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 were taken of the actual watch; please note that the color may vary slightly due to lighting reflections, shadows, or direct light during the photo shoot.
IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, nato straps, etc., it is possible to remove links or adjust size with the appropriate tools. If you are not able to do it yourself, please consult a professional.
All automatic watches require winding from the crown on first use as wrist movement alone is not sufficient to fully wind the watch
RULE FOR ALL WATCHES WITH DATE
To avoid potential damage to the movement, 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; to set the time you need to gently unscrew the crown counterclockwise. Remember to securely screw the crown back after adjusting.)
