Ulysse Nardin [Super] Freak Sets New Benchmark with 511-Component Double Tourbillon Movement
Ulysse Nardin Redefines Complexity with the [Super] Freak
At Watches & Wonders 2026, Ulysse Nardin unveiled the [Super] Freak (ref. 2520-500LE-3A-BLUE/3A), a watch that pushes the boundaries of mechanical watchmaking with a staggering 511 individual components — 97% of which remain in motion during operation. Limited to just 50 pieces worldwide and priced at $393,600 USD, the [Super] Freak represents the most technically complex time-only watch the brand has ever produced.
According to aBlogtoWatch, the watch marks the 25th anniversary of the original Freak platform, which debuted in 2001 as a revolutionary crown-less, dial-less, and hand-less timepiece. The [Super] Freak takes this legacy to unprecedented heights by introducing a dual tourbillon system for the first time in the collection's history.
Technical Breakthroughs: Twin Tourbillons and Patented Gimbal System
The heart of the [Super] Freak is the Caliber UN-252, which features two tourbillon-balance assemblies arranged in a V-configuration. These tourbillons interface with a patented gimbal mechanism — a 4.8mm, 11-piece component that averages the beat rate from both tourbillons before transmitting it through a central driveshaft to a rotating seconds display.
Key technical specifications of the [Super] Freak include:

The Patented Grinder Winding System
The [Super] Freak employs Ulysse Nardin's specially patented Grinder winding system, which uses four spring-loaded levers to harvest energy from the slightest wrist motion. This ultra-gentle approach is critical for protecting the delicate 320-part carousel, which weighs just 3.5 grams. The system is designed to prevent over-winding — a potential threat to the movement's intricate internal architecture.
The time display is achieved through a wing-shaped hour indicator crafted from Nanosital, a proprietary glass-ceramic composite, with the minutes indicated by the carousel's full rotation. For the first time in Freak history, a dedicated seconds indication appears near the tip of the minutes hand via a rotating cylinder.
Assembly and Manufacturing Challenges
Ulysse Nardin has stated that the [Super] Freak's movement must undergo a unique assembly process: it is built, tested, disassembled, adjusted, and assembled again before final delivery. This multi-stage quality control process ensures that all 511 components interact within the tight tolerances required for chronometric performance.
The use of exotic materials — including Nanosital for the display disc, titanium for internal components, and sapphire crystal requiring exceptional height to house the towering mechanism — adds further complexity to production. The case features a linearly brushed treatment on its 18K white gold surfaces, giving the watch an unexpectedly tool-like appearance for a high complication piece.
Industry Context: Innovation at the Upper Limits
The [Super] Freak's release comes amid a broader trend of watchmaking brands pursuing extreme mechanical complexity. While most modern tourbillons operate at 2.5Hz to 4Hz frequencies, Ulysse Nardin's dual-tourbillon approach represents a different kind of innovation — one focused on averaging precision across two independent oscillators rather than increasing beat frequency alone.
The $393,600 price point places the [Super] Freak among the most exclusive time-only watches on the market, competing with pieces from brands like Greubel Forsey and F.P. Journe in the haute horology segment.
Frequently Asked Questions
Q: What makes the [Super] Freak different from previous Freak models?
A: The [Super] Freak introduces twin tourbillons for the first time in the Freak collection, along with a patented gimbal averaging system and a rotating seconds display — features not found in any previous Freak variant.
Q: How does the Grinder winding system work?
A: The patented Grinder system uses four spring-loaded levers that respond to the slightest wrist motion, transferring energy gently to the mainspring. This prevents damage to the delicate 3.5-gram carousel assembly.
Q: Why must the movement be assembled, disassembled, and reassembled?
A: The extreme component density (511 parts, 97% moving) requires multiple rounds of adjustment to ensure all parts interact within specified tolerances. This multi-stage process is necessary for chronometric accuracy.
