This is the new Franck Muller Giga Tourbillon, and what a looker it is. The aptly named watch features a whopping 20mm diameter tourbillon which dominates the entire lower half of the watch. Franck Muller claims this it the largest tourbillon ever incorporated into a wristwatch. The highly skeletonized watch is awe inspiring with its sweeping curves and arcs, the focal piece being the elegant “M” (and the somewhat hard to see “F”) that sits directly on top of the tourbillon cage — lest you forget this piece is anything other than a Franck Muller!
