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 on the actual watch; please note that color may show slight tonal variations due to light reflections, shadows, or direct light during shooting.

IMPORTANT NOTE FIRST USE
For all watches with steel bracelets and leather, rubber, Nato straps, etc., it is possible to remove links, adjust/polish, but only with the necessary tools. If you are not able to do it yourself, please consult a professional.
All automatic watches must be wound when first used; relying on wrist movement alone is not enough 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 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 need to gently unscrew the crown counterclockwise. Don’t forget to reseal the crown properly after adjusting).
