Blancpain Villeret Semainier Grande Date 8 Jours 6637 3631 55B

This Blancpain timepiece is powered by Caliber 3738G2, a 378-part self-winding movement. It is equipped with three mainspring barrels guaranteeing an 8-day power reserve, as well as a titanium variable-inertia balance with gold micrometric regulation screws and a balance spring in silicon. This material recently introduced within the watch industry offers several important advantages. Firstly, its low density makes it lighter and thus more shock-resistant. In addition, it is impervious to magnetic fields. The resulting balance spring is ideally shaped, thereby ensuring improved isochronism performance of the movement, which in turn leads to enhanced timekeeping precision.

The sapphire case back provides a clear view of the finely hand-finished movement and the gold winding rotor with its honeycomb guilloché pattern. This new creation combining innovation and watchmaking tradition is offered with a hand-stitched chocolate-colored alligator strap.
