WHAT’S INCLUDED
Full set (The watch box may differ from the photos depending on stock available in our warehouse at the time of shipping, but we guarantee that it is the brand’s original box.)
INFO
The photos were taken of the actual watch. Please note that the color may vary slightly in tone due to light reflections, shadows or direct light on the watch during photography.
IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, NATO, etc. straps, links can be removed and straps can be pierced/shortened yourself, but only with the proper tools. If you are unable to do this yourself, we kindly ask you to consult a professional.
All automatic watches need to be wound via the crown when first used; wrist movement alone is not sufficient to maintain the necessary power reserve.
RULE FOR ALL WATCHES WITH A DATE DISPLAY
To avoid possible damage to the watch mechanism, please do not set the date using the crown when the watch time is between 9:00 p.m. and 3:00 a.m. We recommend setting the date using the crown when the time is between 3:05 a.m. and 8:55 p.m. (Some watch models have a screw-down crown; to make adjustments, gently unscrew the crown counterclockwise. Remember to screw the crown back down securely after making the desired adjustments.)
