INFO
The photos are taken on the actual watch; please note that color may vary slightly due to reflections of light, shadows or direct light on the watch during shooting.
IMPORTANT NOTE FIRST USE
For all watches with steel bracelets and leather, rubber, nato straps, etc., it is possible to remove links, punch/shorten with the necessary tools; if you are not able to do it yourself, please kindly contact a professional.
All automatic watches at first use must be wound from the crown as well; wrist movement alone is not sufficient to maintain the required power reserve.
RULE FOR ALL WATCHES WITH DATE
To avoid possible damage to the watch mechanism, please do not set the date with the crown when the time is between 21:00 and 03:00. It is recommended 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 adjustments you need to unscrew the crown gently counterclockwise. Don’t forget to tighten the crown properly after adjusting.)
