The dressy Dubey & Schaldenbrand Grand Dome R92 Vintage is powered by a NOS Valjoux 92 hand-wound caliber and will soon be offered as a super limited edition of just 16 pieces with only one or two pieces available to US-based customers.

The legendary Valjoux 92 hand-wound caliber was first introduced more than 60 years ago.

Sporting a unique swivel pinion design invented by Edouard Heuer (yes, the very same Edouard Heuer: a master watchmaker who founded Uhrenmanufaktur Heuer AG in 1860, patented his chronograph design in 1882 and a highly efficient “oscillating pinion” coupling system that is used even in modern chronograph calibers in 1887) himself back in the 1880s, the movement still enjoys a lot of attention from independent watchmakers that use it to create their own limited-edition models (Carl F. Bucherer employed this beautiful movement for its exceptional Manero Tribute to MaBu bi-compax chronograph in rose gold).

For this Dubey & Schaldenbrand Grand Dome R92 Vintage model, D&S’s artisans took 16 of these old calibers and skeletonized them to the barest minimum leaving just enough rhodium-plated brass to hold the numerous gears without the mechanism bending like a dry leaf. The most affected was, of course, the base plate, which is clearly visible through a circular cutout on the timekeeper’s satin-brushed and black rhodium-plated dial.

The plate was skeletonized to such an extent that some people will have a hard time reading data on the two sub-dials at 3 and 9 o’clock, although the blued hands themselves are still contrasting enough to be discerned in the maze of gears, pinions, and hair-thin bridges.

Of course, given the price level of both models (the Datograph is around 6 times more expensive than the Grand Dome R92, which is going to be offered at “just” $16,700 USD), the comparison is not that relevant after all, but the watch is still expensive enough for a potential owner to demand a lot more elaborate finish of the vintage caliber, especially given the fact that the caliber is the main selling point of this otherwise highly attractive time measuring device.
