With our Brive precision pendulum clocks, we have remained true to our
policy of not just using tried and true methods but improving these methods
with the help of cutting-edge technology. This has allowed us to integrate
several features into our Brive clocks which were formerly impossible
Due to the difficulties involved in combining a one-year power reserve and
a central second hand, these two features are rarely found together in one
clock. Brive's combination of not only these two features but also an anchor
that is not laid on its own axle but attached to the pendulum is absolutely
unique. Contrary to common practice, the works are driven by two tungstenweights
using an epicycloidal gear so that the clock continues to run even
while being wound. The rod of the pendulum, which weighs seven kilos, is
made of invar and bears an air-pressure and temperature compensator.
The escape-wheel is made of a very light alloy and driven by a delicate
spiral spring in its hub. The escapement is highly efficient due to minimal
inertia. Because of the gears' wear-resistant diamond coating, friction loss in
the gears is negligible.
Expert craftsmanship is visible in many of the details: the Geneva stripes
on the plates, the polished chatons, wheels and their spokes. The case consists
of fine, highly polished nickel-coated brass framing with facetted glass
Brive's technical innovations, high-quality materials and meticulous
handiwork combine to make it not only exclusively valuable but also extremely
reliable due to its lasting precision.
