Care &

Maintenance Instructions: To maintain the pristine mechanical precision and preserve the advanced architectural finish of your Swiss automatic diver timepiece, please follow these professional guidelines:

Mechanical Motion &

Winding Protocol: Since this is a self-winding mechanical watch, it requires regular bodily movement to stay wound. For optimal performance, wear the watch daily. If the watch has been stored or has completely stopped, gently unscrew the security crown and turn it clockwise 20 to 30 times before wearing to manual-wind and fully re-engage the power reserve.

Screw-

Down Crown Operation: To guarantee the full integrity of the monstrous 30 bar water resistance, ensure the heavy-duty security crown is completely tightened and locked securely back against the steel case after setting the time. Never operate, adjust, or unscrew the crown underwater or when the watch body is wet.

Rinsing &

Maintenance: After any saltwater marine activities or heavy exposure to chlorinated swimming pools, thoroughly rinse the entire watch body and steel bracelet with clean, fresh water to eliminate corrosive salt crusts, chemical films, or sand residues, and wipe dry with a soft cloth.

Allergy Notice: Although the premium 316L stainless steel alloy undergoes standardized comprehensive anti-allergenic processing, individuals with hyper-sensitive skin profiles should monitor their skin and discontinue wear immediately if unexpected irritation occurs.

Pre-

Wear Inspection: Please thoroughly examine the structural finish, bezel clicking alignment, and secure clasp operation prior to initial wear, as post-wear service will be managed entirely via official certified factory repair channels.
