INFO
The photos were taken on the actual watch; note that color may vary slightly due to light reflections, shadows, or direct light on the watch during shooting.
IMPORTANT NOTE FOR FIRST USE
For all watches with a steel bracelet and with leather, rubber, nato, etc., it is possible to remove links, pierce/shorten with the do-it-yourself method, but only with the necessary tools. If you are not able to do it yourself, please consult a professional.
All automatic watches need to be wound at first use even if wearing the watch to your wrist; the movement alone is not enough to maintain the required power reserve.
RULE FOR ALL WATCHES WITH A DATE
To avoid possible damage to the movement, please do not set the date using the crown when the watch 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; settings require gently unscrewing the crown counterclockwise. Don’t forget to securely screw the crown back after adjusting the desired settings.)
