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 are taken on the actual watch; please note the color may show slight tonal variations due to reflections of light, shadows or direct light during the photo shoot.
IMPORTANT NOTE FIRST USE
For all watches with steel bracelets and leather, rubber, nato straps, etc., it is possible to remove links, pierce/shorten with the provided tools, but only with the necessary tools. If you are unable to do it yourself, please consult a professional.
All automatic watches must be wound initially from the crown to start charging; wrist movement alone is not sufficient to maintain the required power reserve.
RULE FOR ALL WATCHES WITH DATE
To avoid potential damage to the watch mechanism, please do not set the date using 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 adjustments, gently unscrew the crown counterclockwise. Do not forget to secure the crown properly after setting.)
