The 30mm. SXH5.01 automatic calibre powering the Antartique Collection has been conceived internally by a multifaceted team. Special attention was given to both performance and appearance, so the movement’s parts are arranged for visual harmony and transparency.

At the root is a free-sprung balance wheel with variable inertia provided by four gold masselotte weights, which enables the highest level of precision tuning for a mechanical watch. The powerful microrotor is made of fully recycled Platinum 950. It was placed off-centre to allow a plunging view into the mechanism. The SXH5.01 runs at a fast 28,800 vph. The single barrel harbours a flat spring wound via the traditional Czapek ratchet wheel with five arms. The timepiece has a power reserve of over 60 hours, a truly remarkable feat for a microrotor.
