Louis Moinet 20-Second Tempograph

In its new 20-Second Tempograph timepiece, Swiss haute horlogerie atelier Louis Moinet merges traditional watchmaking with modern innovation to reveal a magical display of time.

Powered by a new movement composed of more than 260 parts – LM Calibre 39 – this astonishing model boasts a central retrograde hand that performs a fascinating dance in 20-second cycles, before returning to its initial position to resume its progress. Meanwhile, an open worked disc at 9 o’clock in subtly graded shades of white, grey and black, marks off three 20-second segments measuring each minute.

The hours and minutes appear on an off-centred subdial at 5 o’clock, while the balance wheel, gear wheels and retrograde mechanism are all clearly visible. Testifying to the expertise required to give life to such a sophisticated horological composition, the inner bezel ring is adorned with a Clous de Paris hobnail motif in keeping with the finest watchmaking traditions.

This model is issued in a 365-piece titanium edition and in 60-piece iterations of the pink and rose gold variations.
