PACKAGE CONTENT
Complete set (The watch box may differ from the photos depending on stock available in the warehouse at the time of shipment, but we guarantee the original brand box)
INFO
Photos are taken on the actual watch; please note that color may vary slightly due to lighting reflections, shadows, or direct light during photography.
IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, NATO, etc., it is possible to remove links, drill/shorten with DIY methods, 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 by the crown on first use; wrist movement alone is not enough to maintain the required power reserve.
POLICY FOR ALL DATEWATCHES
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 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. Remember to securely screw the crown back after changing the settings.)
