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 box of the brand)

INFO
The photos were taken on the actual watch; please note that colors may vary slightly in shade due to lighting reflections, shadows, or direct light during shooting.

IMPORTANT NOTE FOR FIRST USE
For all watches with metal bracelets and straps in 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, please seek a professional.
All automatic watches must be charged at the first use also by winding the crown; simply moving the wrist is not sufficient to maintain the required power reserve.

RULE FOR ALL WATCHES WITH DATE
To avoid possible damage to the watch 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 you may need to gently unscrew the crown counterclockwise. Don’t forget to securely screw the crown back after making the desired adjustments.)
