The fusée-and-chain transmission compensates for the declining spring force, keeping the effective torque constant across the entire power-reserve period.For this purpose, the drive function, usually handled by the mainspring barrel alone, is taken over by two components: the mainspring barrel and the adjacent tapered fusée.The replica Breitling A2432212-G5-426A Men's watch two components are connected by a dainty chain which in the case of the RICHARD LANGE "Pour le Mérite" consists of 636 individual parts.At one end, it is attached to the broad lower end of the fusée and at the other to the exterior of the spring barrel.A slot is milled into the conical suce of the fusée that leads to the narrowest point, much like a spiral path that leads to the summit of a mountain.

When the watch is being wound, the chain unreels from the outer wall of the barrel and wraps around the fusée until - if we stick with our metaphor - it arrives at the summit of the mountain.In this state, the radius of the fusée, i.e.the magnitude of its leverage, is small but the torque delivered by the mainspring is large.As the mainspring replica Breitling A773 Ladie's watch gradually unwinds, its power diminishes.But as the chain unreels from the fusée and back onto the barrel, the length of its lever- the effective radius of the fusée - increases by the exact same measure as the spring's torque decreases.The result is constant torque at the fusée's arbor and therefore constant amplitude of the balance.

A Horological Opus This complex system can only function flawlessly if three additional precautions are taken.The first one is a system that blocks the winding process just before the mainspring is fully wound and thus prevents the chain from tearing.In this mechanism, the vertical motion of the chain is used to actuate an intricate system of levers that block the ratchet wheel at the right moment.The second precaution is a replica Breitling Navitimer Cosmonaute Men's watch mechanism that stops the movement before the mainspring is fully relaxed.This function is assumed by a modified power-reserve wheel that controls a stop lever.After exactly 36 hours, the lever drops into a recess in the wheel.Assisted by a spring, the longer arm of the lever moves into the engagement radius of a specially shaped finger seated on the fourth wheel arbor.
