Care &

Maintenance Instructions: To protect the highly sensitive mechanical caliber and maintain the pristine architectural finish of your Swiss automatic aviation timepiece, please follow these professional guidelines carefully:

Mechanical Motion &

Winding Protocol: Since this is a self-winding mechanical watch powered entirely by kinetic energy, it requires regular bodily movement to stay wound. For optimal performance, wear the watch daily for at least 8 hours. If the watch has been stored for an extended period or has completely stopped, gently turn the primary crown clockwise 20 to 30 times before wearing to manual-wind and re-engage the power reserve.

Security Crown Operation: To guarantee the full integrity of the robust lifestyle moisture-proofing framework, ensure the oversized security winding crown is completely tightened and locked securely back against the steel case after adjustments. Never operate or adjust the crown underwater or when the watch body is wet.

Textile Strap Maintenance: The high-performance black textile strap is engineered for tactical durability. To maintain its deep color and material integrity, rinse the strap thoroughly with clean fresh water if exposed to excessive sweat or salt environments, and allow it to air dry fully.

Chemical &

Cosmetic Avoidance: Prevent direct contact with volatile chemical solvents, industrial detergents, hairsprays, or intense alcohol-based perfumes, as volatile chemical films can prematurely degrade the high-performance waterproof seals over time.

Pre-

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