H. Moser & Cie. Perpetual Calendar MD Limited Edition

For the first time in its history, H. Moser & Cie. has created a perpetual calendar with two windows displaying the date and month. The aim of this development is to offer optimal legibility in the brand’s sportiest line: Pioneer.

The Pioneer Perpetual Calendar MD features a steel case water-resistant to 120 metres, enabling it to display the time under any conditions, whether on land or underwater.

In 2015, H. Moser & Cie. launched the Pioneer collection. This contemporary collection, imbued with a pioneering, adventurous spirit, was the obvious choice to accommodate the brand’s new perpetual calendar with dual window display.

On its dial, this new timepiece boasts two large windows to display the date and month and two discs featuring the Flash Calendar function, which changes instantly when necessary. The date can be set at any time of the day, forwards or backwards, with no risk to the movement.

The Pioneer Perpetual Calendar MD is an innovation par excellence, available in two models with bold colours: the first features the Funky Blue dial with traditional indexes and markers; the second is dressed in a brand new colour – Burgundy – and stripped of almost all indications except for the dots that mark the hours.

An offset small second sits at 6 o’clock, and a power reserve indicator at 9 o’clock, along with the leap year cycle indicator, which is concealed on the movement side.

The leaf-shaped hands are partially skeletonised and filled with Superluminova®, as are the hour marker dots on the flange.

At the heart of the Pioneer Perpetual Calendar MD beats a new Manufacture calibre. A complex marvel of ingenuity, the HMC 808 hand-wound movement offers a comfortable power reserve of at least seven days thanks to its double barrel.
