GPHG 2017 Mechanical Exception category

Hard times? Judging by the numerous and unusual complications on the watches preselected for the Grand Prix de Genève, maybe not.

The Mechanical Exception category of the Grand Prix d’Horlogerie de Genève brings together the ultimate in sophistication and innovation. But that’s the thing. Sophistication and innovation represent two very different kinds of watches. A watch is considered sophisticated when it offers many different indications. It’s innovative when it offers new ways of doing things, and this could apply to simple functions as much as to complicated ones. Neither approach is better than the other – they are both vital to the progress of watchmaking. All we can do is sit back, and wait for the jury to announce which they have decided to reward this year.

The Tourbograph Perpetual “Pour le Mérite” offers a bundle of complications that is unusual these days for its breadth, but also because it represents a catalogue of everything A. Lange & Söhne can do. The Tourbograph, a tourbillon and chronograph combined, has been around for some time, but here Lange has added its perpetual calendar, plus a fusée-and-chain transmission. The constant force mechanism is what the “Pour le Mérite” designation refers to, in the Saxon company’s lexicon. Girard-Perregaux has chosen a similar approach to complication, but with the accent on three-dimensionality. The tourbillon of the Planetarium Tri-Axial pivots around three axes, performing spherical revolutions. Alongside the tourbillon there is a world globe that rotates at a more stately pace, as well as a moon phase indication and an off-centre time display.

Vacheron Constantin has pushed the envelope with 23 complications. The Celestial Astronomical is a mechanical computer for astronomical functions and indications. This one-of-a-kind piece (further examples may be commissioned on request) represents a unique and uniquely comprehensive catalogue of functions. It nevertheless remains portable, legible and practical, with a 3-week power reserve and, incredibly, a thickness of just 13.6 mm. We have seen many thicker watches offering far fewer complications.

In recent years, much horological innovation has focused on minute repeaters, and two of the most remarkable initiatives in this direction are going head to head in this category. The Audemars Piguet Supersonnerie incorporates the sound amplification concepts we have already seen in the grand complication Royal Oak Concept, but inside a Jules Audemars case (this watch marks the launch of a new iteration of this model). Here, however, it’s all about the sound. The apertures in the caseback are connected to a copper resonance membrane (providing acoustic resonance, not frequency).

In opposition, Chopard is presenting its most innovative watch, the watch to which the company has devoted more development efforts than any other in its history: the Full Strike. What makes it different are its many safety features, its considerable striking reserve, and above all, its unique approach to sound generation. In this L.U.C watch, the two gongs that create the sound are carved from the same block of sapphire as the watch crystal. As they are of a single piece, they behave like a loudspeaker, producing a sound that is crystal clear, literally.

But innovation can take other forms, for instance in new approaches to abstruse concepts such as resonance. Armin Strom created a stir with its Mirrored Force Resonance. It improves the precision of a double-escapement system by using resonance to synchronise the two components. In this instance, the two escapements are linked by a spring-shaped component, which causes them to synchronise. The watch design as a whole is also extremely striking.

Whether the approach comes from a big brand or a small firm, whether it’s classical or iconoclastic, elegant or cutting-edge, this category brings together some major statements in terms of technology, image and, above all, philosophy.
