Ludovic Ballouard “Upside Down” Complication Watch in Platinum

After many years working with some of the world’s greatest watchmakers – most recently with François-Paul Journe on his magnum opus Grande Sonnerie – in 2009 Ludovic Ballouard decided to become independent to develop his own horological creations. His innovative “Upside Down” heralds a completely new way to indicate the time by astonishingly rotating individual hour numbers on cue.

While the idea of indicating the time by having the correct hour right side up, while the other 11 displayed numbers are upside down looks relatively simple, the fact that it had never been done before is a testimony to the technical difficulty of realising the complication.

When the minute hand precisely reaches the 12 o’clock position, the past hour number instantaneously turns 180 degrees upside down. Simultaneously the new hour turns right side up. The rotation of these two tiny hour disks is faster than the eye can follow, and by using Maltese crosses to control the rotation mechanisms, time-keeping precision is not affected.

No easy task as it necessitated drilling 12 minute holes through the movement plate for the 12 tiny pinions that control the hour discs.

The platinum case is a meticulously thought-out work of art in itself. Rather than the straightforward vertical sides or slightly outward curves commonly found in timepieces, the case sides of the “Upside Down” curve slightly inwards. This design not only protects against scratches, but also offers a tactile pleasure when running a finger lightly over the unexpected line.

The platinum crown – another unusual feature of the “Upside Down” as the majority of platinum watches have white gold crowns for ease of manufacture – is protected by sleek buttresses on either side.
