CONTENTS
Full set (The watch box may differ from the photos depending on warehouse stock 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 reflections of light, shadows, or direct light during shooting.
IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, NATO, etc., it is possible to remove links, pierce/shorten with DIY tools, 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 at first use; merely wearing the watch due to wrist movement is not enough to keep the required power reserve.
RULE FOR ALL WATCHES WITH DATE FUNCTION
To avoid possible damage to the 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, gently unscrew the crown counterclockwise. Don’t forget to securely screw the crown back after adjusting.)
