CONTENT
Complete 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 live on the watch; please note that color may vary slightly in shade due to reflections of light, shadows, or direct light on the watch during shooting.
IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, NATO, etc., links can be removed or the strap shortened with tools if you can do it yourself; if you’re not able to do it yourself, please consult a professional. All automatic watches must be wound at first use; relying only on wrist movement is not enough to maintain the required power reserve.
RULE FOR ALL WATCHES WITH A DATE
To avoid possible damage to the movement, please do not set the date with the crown when the time on the watch 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; to adjust, gently unscrew the crown counterclockwise. Don’t forget to reseal the crown properly after making the desired adjustments.)
