Description
B.R.M. Watches FF39-40 Black Titanium FF39-40-TN-LFN-J. Full Floating, a movement in total, freefall like suspension. The watch manufacture with a sporty DNA has reinterpreted two fundamentals of the mechanical world: silentblocs and belts. In addition to their fine aesthetics, these innovations make the FF39-40 the first automatic watch protected against both vertical and horizontal shocks. The concept is all in the name: FF, for Full Floating. Five ribbed silentblocs, each 1.2 mm thick, and two belts of 1 mm toroid radius, their nitrile formed in molds specially developed at our workshops work together to snuff out all vibrations and protect the watch’s engine-like core: the floating movement. A self-supporting casing ring of hard-anodized Fortal HR enables the five silentblocs to hold the plane vertically. The stainless-steel BTR micro-screws, all machined by material removal, serve to compress a micro-fine carbon strut bar of 0.5 mm, limiting the cage’s lateral displacement within the case. Meanwhile, two belts provide horizontal stability for the automatic movement, itself secured with self-centering, screwed-down braces. The bearing, pressed into a bronze shaft, is screwed into the rotor, to keep the overall structure concentric. The movement’s bored and equilibrated cylinder, with its constant and secure motion control, optimizes the force of the spring, and guarantees a power reserve of approximately 38 hours. The bored, equilibrated, and decorative ratchet offers a superb look of the movement when viewed from directly above. The balance, machined from a bar of Fortal HR and eloxated, is dynamically equilibrated in the 6 positions, for perfect chronometry. All the features above, together with the functional complications within, constitute an ingenious system that seems to render the movement weightless, and make the FF39-40 into a chronometric UFO of highly mechanical aspect.
