Full set (The watch box may differ from the photos depending on stock availability at the time of shipping, but we guarantee the original brand box)
INFO
The photos are taken real on the watch; please note that color may vary slightly in hue due to reflections of light, shadows, or direct light on the watch during shooting.
IMPORTANT NOTE FOR FIRST USE
For all watches with steel bracelet and leather, rubber, nato, etc., it is possible to remove links, punch/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 on first use must be wound also via the crown; simply moving the wrist is not enough to maintain the required power reserve.
RULE FOR ALL WATCHES WITH DATE
To avoid potential 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 when the time is between 03:05 and 20:55. (Some models have a screw-down crown; to set, gently unscrew the crown counterclockwise. Do not forget to screw the crown back in securely after adjusting.)
