As anticipated, the new number 12 version of the Opus from Harry Winston again fulfilled expectations. The Opus 12 once more defined the conventional rules of watchmaking to overturn the perception of time. Inspired by the Copernican revolution which postulated that the earth spins around the sun as well as on its own axis, this watch turns time upside down. The passing of time is no longer displayed by hands placed at the centre of the dial, but instead by a pair of peripherally driven hands pointing inwards from the dial circumference. At each change of hour, the movement powers the successive rotation of the hands, while the lower part of dial features a retrograde five-minute display, and a floating small seconds indication sweeps over a power-reserve indicator. A truly surprising mechanism stemming from cooperation between watch developer Emmanuel Boucher and designer Augustin Nussbaum.
