Introducing: Breguet Celebrates the 225th Anniversary of the Tourbillon with Four New Releases, And the Return of a Collector Favorite (Live Pics)

You’re looking at a 35mm by 9.2mm manually-wound tourbillon in Breguet gold (also available in platinum) with a 43mm lug-to-lug. The dimensions of the original were about 36mm by 9.5mm, so this is not only slightly smaller and thinner, but now has 30m of water resistance. As you’ll notice in the photos, Breguet gold (a proprietary alloy) sits somewhere between yellow and rose and tends to shift in the light, picking up tones from its surroundings.

The single, bone-shaped cross-through bridge from Cal. 558 has been redesigned as a double, rounded-off, polished “arched” bridge, which extends to the edge of the dial on both the front and the back. The watch still has a 2.5Hz beat rate, which allows the 3 hands on the tourbillon to indicate 20-second intervals. The power reserve is now 60 hours. And the movement has been redesigned for antimagnetism, featuring a Breguet Nivachron balance spring and a silicon pallet lever. Breguet tells me 41% of the parts are new. As for finishing, the movement now features a newly designed, unique guilloché called “Dent de Vaulion,” which is named for the pattern on the Lac de Joux as viewed from the imposing Dent de Vaulion at the northern edge of the Vallée de Joux, where Breguet is headquartered. The edge of the movement features the text “Brevet du 7 Messidor An 9” and “Tourbillon 225e Anniversaire.”
