ABF Edition — Fluororubber Tailored Nylon Strap
The ABF execution of the Franck Muller Grand Central Tourbillon CX 40 T CTR represents a significant technical milestone in replica horology, successfully relocating the tourbillon to the center of the dial. Housed in a meticulously milled carbon fiber tonneau case, this reference balances complex geometry with a verified weight of 125.6g, ensuring substantial wrist presence without compromising ergonomic wearability.
At the core of this piece is a customized 40t-ctr automatic winding clone caliber. To accommodate the central rotating escapement, ABF has heavily modified the pointer gear train, mounting the hands on the periphery of the tourbillon carriage so they appear to float above the dial. Operating at 28,800 vph, the movement delivers a power reserve of approximately 36 hours, prioritizing steady torque delivery to the oversized tourbillon cage.
The redesigned case features slender, continuous lines where the upper and lower ends of the sapphire crystal extend directly to the lugs, creating an expansive viewing aperture. The carbon fiber composite displays correct black and gray striations, complementing the lacquered dial’s embossed spiral guilloché texture. The entire assembly measures a substantial 19mm in thickness, remaining faithful to the aggressive profile of the genuine article.
