Care &

Maintenance Instructions: To protect the delicate internal components and maintain the pristine two-tone finish of your Swiss automatic high-end timepiece, please observe these 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 for at least 8 hours daily. If the watch has been stored for an extended period or has completely stopped, gently unscrew the 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 robust 30 bar water resistance, ensure the screw-down crown is completely tightened and locked securely back against the steel case after setting the time or manual winding. Never operate, adjust, or unscrew the crown when the watch is wet or completely submerged.

PVD Coating &

Chemical Avoidance: The premium red gold PVD layer is highly durable but can be affected by prolonged exposure to harsh industrial chemical agents, industrial detergents, high-concentration volatile gases, or intense alcohol-based perfumes. Avoid direct abrasive friction against hard metal fixtures to protect the polished gold facets from superficial scratches.

Allergy Notice: Although the premium 316L stainless steel alloy and PVD layers undergo standardized comprehensive anti-allergenic processing during manufacturing, 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, dial alignment, and operational condition of the watch prior to initial wear, as post-wear service will be managed entirely via official certified Swatch Group factory repair channels.
