CONTENT
Complete 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 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 steel bracelet 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 seek a professional.
All automatic watches must be wound at first use; winding from the crown is required because wrist movement alone is not sufficient to maintain the necessary power reserve.

RULE FOR ALL WATCHES WITH A DATE
To avoid possible damage to the watch mechanism, please do not set the date using 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 settings you need to gently unscrew the crown counterclockwise. Remember to screw the crown back in securely after modifying the desired settings.)

LOGISTICS/WAREHOUSE
