INFO
The photos are taken on the actual watch; please note that color may vary slightly due to light reflections, shadows, or direct lighting during shooting.
IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelets and leather, rubber, NATO straps, etc., it is possible to remove links, pierce/shorten with DIY tools; but only with the necessary tools. If you are unable to do it yourself, please consult a professional.
All automatic watches must be wound at first use; relying on wrist movement alone is not sufficient 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 must gently unscrew the crown counterclockwise. Do not forget to securely screw the crown back after making the desired adjustments.)
