FREE SPRUNG BALANCE WITH VARIABLE INERTIA
This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shock and also during movement assembly and disassembly. Hence better chronometric results over time.
The regulator index is eliminated and a more accurate and repeatable adjustment is possible thanks to 4 adjustable small weights located directly on the balance.
In sapphire (thickness: 0.30 mm) with anti-glare treatment (2 sides).
- Bezel side: in sapphire (1800 Vickers) with anti-glare treatment (2 sides)
- Thickness: 1.00 mm
- Case back: in sapphire with anti-glare treatment (2 sides)
- Thickness: at the center 1.00 mm and at outer edges 1.53 mm
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES
This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.
