Care &

Maintenance Instructions: To protect the highly sensitive hand-wound mechanical chronograph components and preserve the pristine architectural finish of your Swiss mechanical luxury timepiece, please follow these guidelines carefully:

Manual Winding Protocol: Since this is a pure hand-wound mechanical watch with no automatic rotor, it requires manual winding to stay operational. For optimal performance and timekeeping stability, turn the crown clockwise every morning 20 to 30 times until you feel a distinct mechanical resistance. Stop winding immediately once resistance is met to prevent damage to the mainspring.

Chronograph

Pusher Operations: To safeguard the delicate stopwatch synchronization wheels from severe structural strain, never press the reset pusher at 4 o'clock while the central seconds tracking hand is actively running; always press the start/stop pusher at 2 o'clock to fully halt the mechanism before resetting. Never operate pushers underwater.

Aquatic Parameters: This luxury model is structurally rated for robust lifestyle moisture resilience (10 ATM / 100m / 330ft) capable of handling rain, splashes, and superficial handwashing, but is strictly not intended for showering, deep diving, saunas, or total submersion. Always ensure the crown is fully pushed back against the case.

Allergy Notice: Although the premium stainless steel chassis and naturally tanned leather strap undergo rigorous anti-allergenic screening 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, sub-dial zero-reset alignments, and movement operation prior to initial wear, as post-wear service will be managed entirely via official certified factory repair channels.
