For all watches with steel bracelets and leather, rubber, NATO straps, etc., it is possible to remove links, punch/shorten with the proper tools. If you are not able to do it yourself, please consult a professional.

It is recommended 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.
