A Tourbillon Walks Into the Future…
Breguet’s Expérimentale 1 reveals a bold new era of high precision watchmaking with its pioneering 10 hertz tourbillon.
Breguet marks its 250th anniversary not with a retrospective but with a provocation. The new Expérimentale 1 is the first chapter in a research-driven line that lifts the curtain on the maison’s R and D workshops.
It wears the silhouette of a Marine watch yet feels more like a working prototype refined into a collector’s piece.
At its core is a world first: a tourbillon running at 10 hertz and powered by a constant force magnetic escapement. Two escape wheels with magnetic tracks interact with a magnetic pallet lever, delivering a steady impulse that is unaffected by the inertia of the tourbillon cage.

The result is remarkable precision, certified at plus or minus one second per day. For a high-frequency tourbillon, this is a breakthrough.
The design is equally uncompromising. A full sapphire dial reveals gold bridges sharpened into architectural lines, hand-polished angles and an unexpected flash of blue from the barrel springs.
Hours sit at six, while seconds float within the tourbillon at twelve, creating a regulator layout that feels both familiar and radically modern.
Calibre 7250, built from 266 components, pairs this innovation with finesse. The twin-level barrels, silicon balance spring and a titanium tourbillon cage weighing only 0.60 grams underscore the technical ambition.

The 43.5 millimetre Breguet gold case introduces refined Marine details such as ALD-treated blue inlays and an interchangeable rubber strap.
The Expérimentale 1 is not a limited edition in spirit but a statement of intent. It signals that Breguet’s next era will lean heavily into physics-driven watchmaking, just as Abraham Louis Breguet once reshaped the field through invention.
This is the maison’s most compelling reminder in years that its future may be as influential as its past.
