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 are taken on the actual watch; please note that color may vary slightly in tone due to reflections of light, shadows, or direct light during the shoot.
IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, NATO, etc., links can be removed, the bracelet can be shortened or adjusted with the proper tools; if you are not able to do it yourself, please seek a professional.
All automatic watches require charging from the crown at first use; merely moving the wrist is not enough to maintain the necessary power reserve.
RULE FOR ALL DATED watches
To avoid potential 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 watch models have a screw-down crown; for settings, gently unscrew the crown counterclockwise. Do not forget to securely screw the crown back after adjusting the desired settings.)
