Description
APPF Audemars Piguet Code 11.59 Tourbillon Openworked 26600CR
A highly technical execution featuring a functional flying tourbillon and accurate double-curved sapphire geometry.
Powered by Custom Caliber 2948 Clone
The mechanical focal point of this replica is the custom Caliber 2948 clone, a manual-winding movement engineered specifically to support a 60-second flying tourbillon. The escapement lacks an upper bridge, providing an unobstructed view of the oscillating balance wheel at the 6 o��clock position. The movement architecture maintains strict vertical symmetry, with the mainspring barrel exposed at 12 o��clock. Bridge finishing involves three distinct grey tones, applying appropriate brushing and chamfering to mimic haute horlogerie standards.
Tourbillon clone movements typically operate within a tolerance of 卤10��15 seconds per day. Due to the complex nature of the rotating escapement, positional variance is minimized, but regular manual winding is crucial to maintain isochronism.
- �� Power Reserve: Approximately 36 hours
- �� Complications: 60-second flying tourbillon, openworked mainspring barrel
- �� Winding Direction: Unidirectional (Manual wind via crown)
Technical Specifications
The case measures 41mm in diameter with a verified thickness of 13.9mm. It features the signature octagonal middle case sandwiched between an ultra-thin round bezel and caseback, resulting in an exceptionally lightweight 80.6g profile.
A deeply skeletonized dial lacking a traditional baseplate. The grey PVD-treated bridges provide structural contrast, while the hands and applied indices offer high legibility against the complex mechanical backdrop.
A hallmark of the Code 11.59, the crystal is vertically curved on its outer surface and spherically domed on the inner surface. This complex geometry is treated with a high-clarity AR coating to eliminate distortion.
The strap utilizes a woven nylon exterior over a calfskin lining for durability and comfort. It connects to the openworked lugs via screwed bars and fastens with an accurately engraved AP folding clasp.
Why APPF for This Reference?
Many collectors ask: ��Why not BBR or generic tourbillon alternatives?��
While BBR is renowned for their Royal Oak tourbillons, APPF has uniquely invested in the Code 11.59 case geometry. The double-curved sapphire crystal produced by APPF is currently the most optically accurate on the market, avoiding the funhouse-mirror distortion seen in lower-tier versions. Furthermore, the 80.6g weight and 13.9mm thickness ensure the piece wears with the correct ergonomic balance.
Full Disclosure: The manual winding feedback on this clone caliber feels slightly stiffer and more abrasive than the buttery smooth action of a genuine AP 2948 movement, and the power reserve is strictly limited to 36 hours.

Collector Q&A
Q: Is the flying tourbillon at 6 o��clock fully functional or just an exposed balance wheel?
A: It is a fully functional 60-second flying tourbillon escapement. The entire cage rotates on its axis once per minute, accurately mimicking the mechanical behavior of the genuine AP Caliber 2948.
Q: How accurate is the double-curved sapphire crystal on this APPF version?
A: APPF has heavily invested in replicating the Code 11.59��s signature crystal. It correctly curves vertically from 6 to 12 o��clock on the exterior while remaining spherically domed underneath, providing the necessary optical illusion over the openworked dial without excessive edge distortion.
Q: What are the exact dimensions and weight of this specific replica?
A: This APPF model measures exactly 41mm in diameter and 13.9mm in thickness. Thanks to its dual-tone alloy and steel construction, it weighs a remarkably lightweight 80.6g, closely matching the ergonomic feel of the genuine piece.
Q: What is the primary limitation of this Caliber 2948 clone movement?
A: The most notable limitation is the power reserve and winding feel. While the genuine AP caliber offers over 65 hours of reserve, this manual-winding clone provides approximately 36 hours and requires daily winding. Additionally, the crown resistance during winding feels slightly stiffer than the genuine mechanism.
