H. Moser & Cie. Unveil the New Pioneer Cylindrical Tourbillon Skeleton

H. Moser & Cie Pioneer Cylindrical Tourbillon Skeleton

H. Moser & Cie. have been killing the dial game recently with the witty Heritage Perpetual Calendar and the sublime Endeavor Lime Concept. However, for their newest watch they’ve reduced the size of its dial to reveal the mechanical goodness below. This is the Pioneer Cylindrical Tourbillon Skeleton.

The word that first comes to mind upon seeing the watch is ‘sculptural’. The skeletonised HMC 811 calibre has sweeping lines that draw your attention to the flying tourbillon at 6 o’clock, which rotates once per minute, functioning as the seconds indicator. What makes it extra special is that it uses technology first seen in the 18th century in marine chronometers: a cylindrical hairspring. A cylindrical hairspring is one that rises perpendicularly around the balance spindle, giving the tourbillon a dancing, three-dimensional look.

In terms of function, when combined with the two Breguet curves that are also present, the hairspring reduces friction on the pivots and improves efficiency. Each cylindrical hairspring is shaped by hand and takes ten-times as long to produce as a traditional hairspring. In order to produce the piece, H. Moser’s sister company Precision Engineering AG had to remaster traditional techniques that aren’t widely used today.

And with all that going on it still has a great 74-hour power reserve, an openworked gold rotor, diamond bevelling and anthracite PVD finishing. You can understand why they want to show it off.

One thing I particularly enjoy about this watch is H. Moser & Cie.’s decision to house it in the Pioneer case. Stainless steel with a diameter of 42.8mm, it’s about as unassuming as it’s possible to get and at total odds with the artistic energy of the skeleton movement. With 120m of water resistance it implies that this is not a watch for special occasions that call on the height of haute horology but rather everyday use and even, as H. Moser themselves have said, adventuring. It’s such an off kilter contrast that shouldn’t work. But it does.

In addition to the skeleton portion of the display, there’s a subdial offset towards 12 o’clock. It has H. Moser & Cie.’s signature blue fumé with their logo in white and large Globolight® hour markers. Globolight®, for the uninitiated, is a ceramic material combined with SuperLuminova® that provides legibility in dark conditions.

On top of that, it’s available on a black alligator leather strap, steel bracelet, rubber strap, textile strap or Kudu leather strap, providing a veritable plethora of finishing touches.
