Additional information
Entirely manufactured in-house, including the hairspring, the balance wheel features an exclusive design feature. On balancing it draws the brand’s SE initials.
A high-end construction, the micro-rotor permits the integration of an ultra-compact automatic winding mechanism. For maximum efficiency, and despite its reduced diameter, winding is bidirectional. This elegant solution ensures the caliber can be admired in all its splendour. The oscillations of the micro-rotor on the dial side add dynamism to the design.
