PERRELET Double Rotor A3004 Watch Movement Kit — Calibre P-101 Automatic, Limited Edition
Overview
The PERRELET A3004 watch movement kit is a limited edition offering centered on the Calibre P-101, an automatic movement distinguished by its parallel double rotor system and 120-degree retrograde seconds complication. Only 25 numbered kits were produced, making this a rare opportunity to acquire a complete PERRELET movement outside of a fully assembled watch. The kit includes the Calibre P-101 movement, a matching black engine-turned dial with applied gold Roman numerals, and a set of hands. All components are signed by PERRELET, confirming authenticity.
The Calibre P-101 is a Swiss-made automatic movement featuring a retrograde seconds display at 6 o’clock, where the seconds hand advances along a 120-degree arc before instantly returning to zero. This function requires precise mechanical design, a hallmark of PERRELET’s technical approach. The movement’s defining feature is its parallel double rotor system, which winds the mainspring bidirectionally from both sides of the bridge, improving winding efficiency. The movement is engine-turned, individually numbered, and fitted with 17 jewels for reduced friction.
This kit is offered as a complete, functioning assembly graded Excellent in our Condition Grading Scale below. It has been inspected by our technician and confirmed to be in good working order. The movement and dial are designed for installation into a custom or donor case, providing an opportunity to integrate a rare PERRELET calibre into a bespoke project. As a limited production item, it represents one of the few ways to acquire this specific movement outside of a fully assembled watch.
Founded in 1777, PERRELET is recognized for its innovations in automatic watch movements, including the development of the double rotor system. The Calibre P-101 continues this tradition, combining technical sophistication with a visually distinct complication. The movement kit is intended for collectors and watchmakers seeking to create a custom timepiece around a rare and historically significant calibre.
Specifications
The official reference for this kit is A3004. The movement is the Calibre P-101, a Swiss-made automatic with a 120-degree retrograde seconds complication and 17 jewels. Its defining feature is the parallel double rotor system, which winds the mainspring bidirectionally. The movement is engine-turned, individually numbered, and marked PERRELET and Calibre P-101.
The included dial is black with an engine-turned finish, featuring applied gold Roman numerals at 12, 3, 6, and 9 o’clock, and gold baton markers for the remaining hours. The retrograde seconds arc is positioned at 6 o’clock, marked with a 120-degree scale. The dial is signed PERRELET in gold at 12 o’clock. The kit includes the movement, dial, and hands as shown in the photographs.
The movement dimensions are proprietary to PERRELET and are not compatible with standard ETA or Sellita case footprints. The dial feet configuration is also non-standard, requiring custom case fitting. The double rotor system may require additional case back depth compared to single-rotor automatic calibres.
Compatibility
This PERRELET A3004 movement kit is a complete, self-contained unit designed for installation into a compatible watch case. The Calibre P-101 has proprietary dimensions, including non-standard dial foot placement and rotor clearance requirements. It is not a direct replacement for ETA, Sellita, or other Swiss-standard calibres such as Frédéric Piguet or Valjoux.
A professional watchmaker must source or fabricate a case to match the movement’s specifications, including stem height, dial feet positions, and rotor swing clearance. The movement’s double rotor system may require a case back with greater depth than those designed for single-rotor automatic calibres. The dial feet positions are non-standard, necessitating custom case modifications or a donor case specifically designed for this calibre.
Notes
- The article is sold “AS IS”. Please read our Warranty Policy before purchasing.
- Any parts not explicitly mentioned in this description or not visible in the accompanying photographs are not included.
- Colors may appear slightly different across various screens and devices so we cannot guarantee an exact screen-to-reality color match.
The watch shown in some photographs is for illustrative purposes only and is not part of this sale. While the movement is in good working order, we recommend a full service—including cleaning, oiling, and timing adjustment—by a qualified watchmaker before permanent installation to ensure long-term reliability.
This limited edition kit provides direct access to a rare PERRELET calibre with a visually distinct double rotor and retrograde seconds complication, offering a unique foundation for a custom timepiece.
