FF 39x40 : Full Floating, a Movement in Total, Freefall-like Suspension

THE INSPIRATION

The B.R.M Chronographes FF39-40 breaks new ground in horology, drawing inspiration from the high-performance engineering to achieve unrivaled shock protection.

This timepiece incorporates elements from the world of mechanical technology: silentblocs and belts, traditionally used to stabilize high-stress machines, adapting them to shield the watch’s automatic movement from both vertical and horizontal shocks. This innovation, which we call Full Floating, is a fitting name for a movement that seems to “float” weightlessly within its case.

Unique Technical Features: Mastering Vertical and Horizontal Stability

The complex architecture of B.R.M Chronographes’ new automatic timepiece blends technical innovation with industrial craft. 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.

Engineered for Endurance: High Power and Precision

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 spacecraft of highly mechanical aspect.

Minimalist Design with a Bold Statement

This watchmaking marvel’s technical complexity, however, stands in contrast to the minimal style of its case. For this special model B.R.M Chronographes has set aside its usual circular shape and opted for an isosceles trapezoid with rounded corners. The result is a futuristic look, thanks in part to the brushed finish and black PVD treatment of the bezel. And yet the keen eye will spot a different house specialty on this model: the screw-on lugs, here redesigned as cylinders.

This beautiful timepiece, with its patented mechanical geometry, is available in titanium or bronze. The watch strap, handcrafted in Alcantara®, sports a half-buckle with B.R.M logo carved from the sustainable metal block, screwed and glued to the bi-component.

Customization and Personalization

B.R.M Chronographes’ commitment to uniqueness shines in the FF39-40 collection, comprising 36 prestigious models, each reflecting individual style. Every detail, from the materials to the case finish, can be tailored to suit the wearer’s preferences.

The FF39-40: A Testament to Watchmaking Innovation

With its Full Floating design (Fabriqué en France), the FF39-40 stands out in its rarity and performance, showc,asing B.R.M Chronographes’ dedication to pushing the boundaries of traditional watchmaking. The FF39-40 doesn’t just keep time — it captures the spirit of high-tech innovation in a wearable work of art.
