CONTENT
Complete 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 color may vary slightly due to light reflections, shadows, or direct light during filming.
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 a DIY kit, but only with the necessary tools. If you are not able to do it yourself, please consult a professional.
All automatic watches need to be wound at first use; relying solely on wrist movement is not enough 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 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 you must gently unscrew the crown counterclockwise. Don’t forget to securely screw the crown back after adjusting.)
