Tourbillon Perpetual Calendar Skeleton 3755PR/1E/9V6

The Breguet Tourbillon Perpetual Calendar Skeleton Ref. 3755PR/1E/9V6 is a remarkable expression of complicated watchmaking from the modern history of the manufacture. Developed around the turn of the millennium and produced in very small quantities, the Ref. 3755 served as one of Breguet’s flagship grand complications, combining a one-minute tourbillon, perpetual calendar, retrograde date and complete skeletonization within an elegant 40mm platinum case.

Few complications are as inseparable from a watchmaker as the tourbillon is from Breguet. Abraham-Louis Breguet patented his tourbillon regulator in 1801, devising the rotating escapement as a means of compensating for positional errors in pocket watches. Two centuries later, the Ref. 3755 places that invention prominently at 6 o’clock, allowing the tourbillon carriage to become both a mechanical regulator and the visual anchor of the entire watch.

Above it sits an extraordinary perpetual calendar. The month and leap-year indication occupy the register at 3 o’clock, while the day is displayed opposite at 9. Across the upper portion of the watch, a serpentine hand travels along a retrograde date scale, instantly returning to the beginning of its arc after reaching the final day of each month. The perpetual mechanism mechanically accounts for months of differing lengths as well as leap years.

Yet the defining characteristic of the Ref. 3755 is the manner in which these complications are exposed.

Rather than conceal its complexity beneath a conventional dial, Breguet transformed the movement itself into the dial. The bridges and plates of the manually wound Calibre 558 QPSQ have been extensively pierced, skeletonized and hand engraved with elaborate motifs. Almost every available surface becomes part of the decoration, while polished bevels and contrasting metallic finishes give the movement extraordinary visual depth.

The remaining silvered chapter rings appear almost to float above the mechanism. Blued Breguet-style hands provide contrast against the warm tones of the movement, while traditional Roman numerals maintain a connection to the visual vocabulary established by Abraham-Louis Breguet more than two centuries ago.

The 40mm case is rendered in platinum, with straight lugs, polished bezels and the manufacture’s characteristic finely reeded caseband. Sapphire crystals front and back allow the movement to be appreciated from either direction, making the Ref. 3755 as much an exhibition of hand craftsmanship as a functional grand complication.

The movement itself also carries an important connection to modern independent watchmaking history. The architecture behind this family of Breguet tourbillon calibres traces to work undertaken during the period when Daniel Roth played an instrumental role in reviving complicated watchmaking at Breguet. The Ref. 3755 can therefore be viewed not only as a showcase of Breguet’s technical heritage, but also as part of the lineage that helped shape the independent watchmaking renaissance that followed.

Today, the Breguet 3755PR Tourbillon Perpetual Calendar Skeleton occupies a fascinating position for collectors. It combines an historically important complication, an intricate perpetual calendar, traditional hand engraving, precious-metal construction and extremely low production in a single watch. It represents an era when Breguet was willing to demonstrate the full extent of its watchmaking ability without restraint — resulting in one of the most mechanically and visually ambitious Breguet wristwatches of its generation.
