Fresh from winning top honors at the 2025 Grand Prix d’Horlogerie de Genève, Breguet has once again pushed the boundaries of watchmaking innovation. The newly launched Breguet Expérimentale 1 is not only the brand’s first high-frequency constant-force tourbillon—it marks the beginning of an entirely new era for the maison.
This groundbreaking timepiece is the debut model from Breguet’s advanced research and development division, produced in a 75-piece limited edition that blends centuries of horological heritage with bold futuristic engineering.
A High-Frequency Tourbillon Powered by Magnetic Resistance
At the heart of the Breguet Expérimentale 1 lies the all-new Caliber 7250, a movement featuring:
- A constant-force escapement operated by magnetic resistance
- Two titanium escape wheels with magnetic tracks
- A magnetic pallet lever, eliminating traditional jewel friction
- A super-fast frequency of 10 Hz (72,000 vph)—more than double the industry norm
- Four mainsprings in dual barrels, delivering a 72-hour power reserve
This magnetic repulsion system produces an ultra-stable impulse to the balance, achieving extraordinary precision. Despite its avant-garde mechanics, the movement is fully certified by the Breguet hallmark, guaranteeing accuracy within ±1 second over 24 hours.
Honoring the Past Through Innovation
Although named Expérimentale, the watch is neither untested nor theoretical. Instead, the name pays homage to Breguet’s long history of experimentation and invention.
Abraham-Louis Breguet’s innovations include:
- The tourbillon (patented in 1801)
- The constant-force escapement (1798)
- The natural escapement
- The shock absorber
- The chronograph’s precursor
- The Breguet balance spring
- The gong spring
The Expérimentale 1 unites two of these historic patents—constant force and the tourbillon—into one remarkable mechanism. Its regulator display recalls references like the Breguet 1747, marking a symbolic bridge from the maison’s archives to its future.
A Contemporary Interpretation of Breguet’s Marine Line
The case, crafted in 18-karat pink gold, follows the distinctive cues of the Marine collection, featuring:
- A 43.5 mm × 13.3 mm profile
- Fluted caseband
- Integrated central lugs
- A rubber strap for modern comfort
- Super-LumiNova detailing across chapter rings and hands
A regulator-style dial separates minutes, hours, and seconds, with the one-minute tourbillon proudly displaying the seconds—a tribute to traditional precision watchmaking.
A Limited Edition for the Collectors of Tomorrow
With only 75 numbered pieces and priced at CHF 320,000, the Breguet Expérimentale 1 is positioned as a collector’s dream—equal parts scientific innovation, artistic heritage, and mechanical mastery.
More than a watch, it is a statement: Breguet is not only preserving its legacy—it is actively reinventing it.
