The case measures in at 44mm, will be available in rose gold, and is water-resistant around 30m. The dial is totally skeletonized with dual balances put against C?tes de Genève stripes, providing a wonderful contrast and additional symmetry. The time zone signs, as with previous versions, differ with Roman and Arabic numerals from an increasingly popular smoked backdrop. I believe these add an eclectic touch to almost equal parts of this watch. Since the motion does feature independent time zone components, each time zone is handled by its crown, or “ears” as some fans refer to them, at 3 and 9 o’clock. Each time zone is placed using its personal crown, while the watch is wrapped solely from the crown at 3 o’clock. Overall, the aesthetic refinements into the dial along with the symmetry of the Arnold & Son DBG Skeleton watch will refresh and breathe new life into the Arnold & Son DBG. It manages to exhibit the complex and impressive details of a very complex timepiece without delving into the “too busy” category that many tend to fall into when tackling such a intricate endeavor. While I could definitely find a white gold or platinum option in the future, I feel that this is a welcome addition to the collection, and one I’d be eager to wear. The Arnold & Son DBG Skeleton Ref. 1DGAP. S10A.C120P will probably be limited to 30 pieces and will carry a price of $38,850 that is really a few million dollars less than what the original DBG see in gold cost.
Rather than the energy from the mainspring flowing directly into the escapement, it has to first pass through Arnold & Son’s constant force mechanism. The controlled power supply charges a small hairspring, which releases a consistent amount of power to the tourbillon once per second. With this mechanism, there will still come a stage once the energy released by the twin barrels and the continuous force mechanism drops below a stage that’s sufficient to maintain a regular output. When this occurs, the watch stops instead of allowing an isochronal error to creep into the timekeeping.In accession to this interesting solution, the Arnold & Son Constant Force Tourbillon features a deadbeat moments complication, which leads to the seconds hand to “tick” rather than sweep as one may expect in a mechanical timepiece. Exceptional consistency is attained thanks to the symmetry of the movement’s structure, as well as the fact that the constant force escapement remains stationary throughout operation, whereas the tourbillon cage moves once per minute. This is in an attempt to decrease the effect of gravity to the escapement’s functioning. Assuming, however, that this watch is not likely to be worn out in the presence of strong magnetic fields (it’s barely acceptable for use on a construction site or while flying a helicopter, for example), the negative perfectly matches the intended application.The Arnold & Son Continuous Force Tourbillon watch is a limited variant of that only 28 will be produced. It’s a 46mm 18ct rose gold case fitted with an anti-reflective sapphire crystal and a sapphire display back. The A&S5119 motion has 39 jewels, a depth of 6mm, a 90-hour power reserve, and operates at 21,600vph. The movement is almost perfectly symmetrical, and all the technical components are observable on the dial-side. The three-dimensional movement architecture is intended to echo the English tradition of marine chronometer construction. The watch is water resistant to 30 metres and includes a hand-stitched brown leather alligator strap. Cost is available on request.
