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
The photos are taken on the actual watch; please note that color may vary slightly due to lighting reflections, shadows, or direct light during shooting.

IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, nylon, etc., it is possible to remove links, drill/shorten with the DIY method, but only with the necessary tools. If you are unable to do it yourself, please seek a professional.
All automatic watches must be wound initially, also via the crown; wrist movement alone is not sufficient to maintain the required power reserve.

RULE FOR ALL WATCHES WITH A DATE
To avoid possible 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 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 you must gently unscrew the crown counterclockwise. Remember to securely screw the crown back after making the desired adjustments.)
