While none of these changes are exactly necessary, the V4 falls into a long and illustrious line of watchmaking innovation, otherwise known as showing off. Critics point out that a weight limited to moving along one axis can capture only a fraction of the energy that one free to pivot 360 degrees can. What they're ignoring is the watch's aesthetic--and the audacity of its design. The V4 won't set watchmaking on its head in the way ultra-accurate, low-cost quartz movements did in the early 1970s, but it may be the biggest innovation since then. Either way, it'll cost you between $6,000 and $12,000.
