A tourbillon I would actually wear
By Marco Bellini, Zurich ยท
Which is why the rotor goes around the outside. If you want a tourbillon and automatic winding in a case 7.45 mm thick, there is no room for a central rotor on top, so Breguet's caliber 581 uses a peripheral one, a heavy ring running around the edge of the movement. It works, and it leaves the tourbillon clear to see from the back.
I'm tired of tourbillons, mostly. In a wristwatch the cage usually exists so a salesman has something to point at. Here at least the engineering problem was real: thin, self-winding, 80 hours of reserve. Breguet solved it.
Platinum, 41 mm, the fluted case band, the blue dial and the hands that carry Breguet's own name. 30 m. Thin platinum marks easily, so be gentle with it.
160,000 to 175,000 USD is the hard part. For that money I'd look at Journe or Lange first, and I suspect most serious buyers will too. Still, of all the tourbillons at this level, this is the one I'd wear to dinner without feeling silly.
