Arnold & Son's design codes, including its dedication to symmetry and impeccable finishing, as well as its skill at skeletonized movements, are on brilliant display in the manual-wind DBG Skeleton. There are two dials of smoky sapphire crystal, each showing a different time zone. The left uses Roman numerals, has open hands and is set with the crown at 9 o'clock, while the right uses Arabic numerals, has closed hands and is set with the crown at 3 o'clock, making the watch very clear to read and easy to set, with no risk of accidentally setting the wrong time zone. At 12 o'clock you'll find a 24-hour dial with an open hand and a closed hand, which can be used to calculate the difference between the time zones, as well as serving as a day/night indicator. There's also an elegant seconds hand shared by both time zones, because thankfully seconds don't vary around the world. This complicated movement was designed and manufactured in-house at its base in La Chaux-de-Fonds and is the first time Arnold & Son has used this complication in its modern era. In addition to being very useful, the movement is absolutely beautiful. The dials, gears and balances form a harmonious composition, and the exceptional finishing includes chamfered bridges with polished edges, satin-finished wheels and Côtes de Genève stripes.
