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 photography.
IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, NATO, etc., links can be removed or adjusted with the necessary tools. If you are not able to do it yourself, please consult a professional.
All automatic watches need to be wound initially from the crown; simply moving the wrist is not always sufficient to fully wind the power reserve.
RULE FOR ALL D-WATCHES WITH DATE
To avoid possible damage to the movement, please do not set the date via the crown when the time is between 21:00 and 03:00. It is advisable to set the date when the time is between 03:05 and 20:55. (Some models have a screw-down crown; for settings gently unscrew the crown counterclockwise. Don’t forget to securely screw the crown back after adjusting the desired settings.)
