Skeleton watches — timepieces whose mechanical movements have been stripped down to their “bare bones” in order to offer the wearer a view of their innermost workings — remained a popular category at this year’s Baselworld watch fair. Here are some notable new skeletons, in a variety of price ranges.
The Arnold & Son UTTE Skeleton, the latest in the brand’s Instrument Collection, is the world’s thinnest skeleton tourbillon watch on the market, with a 42-mm, 5N rose gold case measuring just 8.34 mm thick, containing a manual-wind tourbillon movement just 3.3 mm thick. The movement, Caliber A&S220, is a reinvented version of Arnold & Son’s ultra-thin Caliber A&S200, which retains the base movement’s large, three-dimensional tourbillon cage and lengthy power reserve, but has been heavily modified through skeletonization of key components. These include an all-new mainplate; a totally revised tourbillon cage for the one-minute flying tourbillon, which occupies a massive 14 mm of the movement’s 32-mm diameter; and new skeletonized barrels for ensuring constant force and 90 hours of power reserve. Haute horlogerie finishes abound, including the brand’s hallmark côtes de Genève rayonnantes pattern on the mainplate and bridges. Limited to 50 pieces and attached to a hand-stitched brown or black alligator strap with a rose-gold pin buckle, the watch retails for $76,750.
