"New Watch" Franck Muller Franck Muller launches the Grand Central Tourbillon mid-mounted tourbillon watch Franck Muller launches a new tourbillon watch - "Grand Central Tourbillon", the special feature is the use of a unique "central tourbillon" structure, allowing the slowly rotating tourbillon to become the visual focus on the dial. Cintrée Curvex The barrel-shaped case has been redesigned with slender and smooth lines. The upper and lower ends of the watch mirror extend to the lugs, making the dial more spacious and open. The case is made of carbon fiber with fine texture. The black and gray stripes of carbon fiber create a subtle texture. It's both charming and elegant, yet abstract and casual. The lacquered dial is paired with eye-catching oversized Arabic numerals, and the embossed guilloché texture diverges from the inside out to form a spiral pattern, echoing the rotation of the tourbillon. Since the tourbillon occupies the central position of the dial, the pointer gear train also responds accordingly. After modification, the hands are installed on the edge of the tourbillon, as if suspended above the dial. It is equipped with a self-made FM CX 40T-CTR self-winding movement with a swing frequency of 28800vh, providing a power reserve of up to 4 days. Paired with a fluororubber tailor-made nylon strap and a new version of the special brushed folding clasp.
