CONTENT
Full set (The watch box may differ from the photos depending on warehouse stock at the time of shipment, but we guarantee the original branded box)
INFO
The photos are taken on the actual watch; please note that color may vary slightly due to light reflections, shadows, or direct light during photography.
IMPORTANT NOTE FIRST USE
For all watches with metal bracelets and leather, rubber, nato straps, etc., it is possible to remove links and resize with the proper tools. If you are not able to do it yourself, please consult a professional.
All automatic watches require charging from the crown on first use; wrist movement alone is not sufficient to maintain the required power reserve.
RULE FOR ALL WATCHES WITH DATE
To avoid possible 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 advised 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. Remember to fully tighten the crown after adjusting.)
