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 in shade 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., it is possible to remove links, punch/shorten with DIY tools, but only with the necessary tools. If you are not able to do it yourself, kindly consult a professional.
All automatic watches must be wound by the crown at first use; the movement’s own motion is not sufficient to maintain the required power reserve.
RULE FOR ALL WATCHES WITH A DATE
To avoid possible damage to the mechanism, 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. Do not forget to screw the crown back in securely after making the desired adjustments.)
