INFO
The photos were taken on the actual watch; please note that color may vary slightly due to lighting reflections, shadows or direct light during shooting.
IMPORTANT NOTE FIRST USE
For all watches with metal bracelets and leather, rubber, NATO straps, etc., it is possible to remove links, drill/shorten with DIY tools, but only with the necessary tools. If you are not able to do it yourself, please consult a professional.
All automatic watches on first use must also be wound by the crown; merely moving the wrist is not enough to maintain the required power reserve.
RULE FOR ALL WATCHES WITH DATE
To avoid possible 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 advisable 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 need to gently unscrew the crown counterclockwise. Do not forget to re-tighten the crown after you finish setting.)
