Instead of the power from the mainspring flowing directly into the escapement, it must first pass through Arnold & Son’s constant force mechanism. The already controlled power supply charges a small hairspring, which releases a consistent amount of force to the tourbillon once per second. With this mechanism, there will nevertheless come a point once the power released by the twin barrels and the constant force mechanism drops below a stage that’s sufficient to maintain a normal output. When this happens, the watch stops rather than allowing an isochronal error to creep in the timekeeping.In addition to this intriguing solution, the Arnold & Son Continuous Force Tourbillon comes with a deadbeat seconds complication, which causes the seconds hand to “tick” rather than sweep as you may expect in a mechanical timepiece. Exceptional consistency is attained as a result of the symmetry of the movement’s structure, as well as the fact that the constant pressure escapement remains stationary throughout operation, whereas the tourbillon cage rotates once a minute. This is in an effort to reduce the influence of gravity on the escapement’s functioning. Assuming, however, that this view is not likely to be worn out in the presence of strong magnetic fields (it is hardly suitable for use on a building site or while flying a helicopter, by way of example), the negative perfectly matches the planned application.The Arnold & Son Constant Force Tourbillon watch is a limited edition of that only 28 will be produced. It’s a 46mm 18ct rose gold case fitted using an anti-reflective sapphire crystal and a sapphire display back. The A&S5119 motion has 39 jewels, a depth of 6mm, a 90-hour energy reserve, and operates at 21,600vph. The NAC grey mainplate as well as the palladium-coated bridges are produced from nickel-silver and hand-finished with polished edges and brushed surfaces, gold screw-down chatons, and bevelled and polished screw heads. The motion is almost perfectly symmetrical, and all the technical elements are visible on the dial-side. The three-dimensional motion structure is intended to replicate the English tradition of marine chronometer structure. The watch is water resistant to 30 metres and comes on a hand-stitched brown leather alligator strap.
