Very fine and rare 47 mm Titanium Case .
Automatic movement .
Variable inertia, free sprung balance
This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shocks 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 small adjustable weights located directly on the balance.
Double system barrel
The double barrel system helps to improve the stability of torque over a longer period. This is achieved by using more turns, thereby reducing pressure and friction on the teeth, the bearings and the pivots, resulting in improved long-term performance.
