Geometric beauty lies at the heart of the new Franck Muller Vanguard 7 Days Power Reserve Skeleton, fabricated with an open-worked lucidity that beckons a closer inspection. An intricately detailed architectural piece encased in the emblematic frame of the maison's hallmark series — in either stainless steel or 18K gold — the transparent design peers into a clockwork of hand-polished bridges wherein the manual-winding FM 1740 calibre movement keeps time to the tune of 18,800 vibrations per hour.

Tracing each finely made component reveals the seconds counter at 6 o'clock, closely integrated into the framework of the skeletonised dial to accentuate the watch's artistic element, as well as the expert craftsmanship moulding each line and curve. A watchmaking work of art bolstered by an extended weeklong power reserve, the Vanguard 7 Days Power Reserve Skeleton is a mechanical treasure that fuses performance, consistency and innovation.

The Vanguard 7 Day Power Reserve Skeleton is available at Franck Muller boutiques.
