A winder imposes motion; VIGIL TEMPORIS® accompanies it.
At Maison LAC, we believe that time deserves a sanctuary. The PATRIMOINE model was designed as a total preservation instrument where technology fades away to let the mechanics thrive.

Technology Driven by Haute Horlogerie Standards
Preserving an automatic caliber requires precision. The Fondation de la Haute Horlogerie (FHH) and prestigious houses like Patek Philippe emphasize the need for specific winding cycles to maintain accuracy without stressing the mainspring.
The VIGIL TEMPORIS® system strictly integrates these universal requirements:

VT-START™: A controlled wake-up cycle for progressive mainspring tensioning, preserving the barrel and transmission components.
VT-BIOMOTION™: Biomimetic kinematics inspired by human wear, alternating active phases and rest periods. It ensures a precise distribution of ≈650 TPD (unidirectional) or ≈850 TPD (bidirectional).
Aligning with the Philosophy of Excellence
Iconic brands like Rolex design rotors to capture natural wrist movements. VT-BIOMOTION™ replicates this organic rhythm, ensuring even oil distribution and preventing premature wear.
A Protective Sanctuary: VT-SHIELD™ and VT-ZERO™
To counter modern magnetic interference, the PATRIMOINE cylinder features Permalloy shielding (VT-SHIELD™), a high-permeability alloy used in aerospace.
Furthermore, the VT-ZERO™ feature ensures that your watch is automatically returned to a perfect vertical position at every stop, mirroring its natural rest position.
The Elegance of the Gesture: Smart Crown™ and VT-SILENT™
User interaction is designed as a tribute to traditional watchmaking via the Smart Crown™. The system operates in absolute silence thanks to belt-free direct planetary gear transmission (VT-SILENT™), providing maintenance-free stability.
