CONTENT
Full set (The watch box may differ from the photos depending on stock available at the time of shipment, but we guarantee the original brand box)
INFO
The photos were taken on the actual watch; please note that the color may vary slightly in shade due to reflections of light, shadows, or direct light during shooting.
IMPORTANT NOTE FOR FIRST USE
For all watches with metal bracelets and leather, rubber, nato straps, etc., it is possible to remove links, punch/shorten with DIY tools; but only with the necessary tools. If you are not able to do it yourself, please seek a professional.
All automatic watches on first use must be wound from the crown as 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 from the crown when the watch time is between 21:00 and 03:00. It is recommended to set the date from 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 screw the crown back properly after adjusting.)
