CONTENT
Complete 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 were taken on the actual watch; please note that the color may vary slightly due to light reflections, shadows, or direct lighting 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, pierce/shorten with the DIY method, but only with the necessary tools. If you are not able to do it yourself, please consult a professional.
All automatic watches at first use must also be wound via 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 advisable 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 in after finishing the desired settings.)
