TAG Heuer Monaco V4 Tourbillon Is Driven by Belts

TAG-Heuer-Monaco-V4-Tourbillon_3

TAG Heuer released the world's first tourbillon driven by micro-belts at this year's Baselworld. The TAG Heuer Monaco V4 Tourbillon is an avant-garde marvel to behold; it's powered by the company's in-house 214-piece caliber V4 with 46 jewels, 28,800 vph, 9 micro ball-bearings, and has a power reserve of 40 hours.

The striking case is set in titanium black carbide and has double AR-coated sapphire crystals. The dial itself is marked by two steel v-bridges black-coated. The belt-driven tourbillon is visible at the 9 o'clock position. This presentation comes together on a hand-stitched black alligator strap with black titanium carbide folding clasp and safety push buttons.

The extraordinary timepiece is entirely hand-crafted and assembled in TAG Heuer’s Haute Horlogerie workshops in La Chaux-de-Fonds, Switzerland.

It's been 10 years since TAG Heuer released its first belt-driven watch. No other watch company has mastered belt-transmission technology. But it's one thing to build concepts and another to build construction-grade models. At the time of this writing, there is no word as to whether this concept will make it into production.
