INFO
The photos are taken on the watch; please note that color may vary slightly 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., it is possible to remove links, poke/shorten with the necessary tools. If you are not able to do it yourself, please kindly contact a professional.
All automatic watches on first use must be wound from the crown as well; only the movement of the wrist 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 on the watch is between 21:00 and 03:00. It is advisable 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 you may need to gently unscrew the crown counterclockwise. Don’t forget to securely screw the crown back after you have made the desired adjustments.)
