All sorts of systems had been dreamed up before the famous Swiss lever escapement was presented in wristwatches, and became more or less standard. Yet it suffers from one drawback: it can only give back the energy it receives from the barrel, which
diminishes with time. This energy, which defines its timekeeping accuracy, is too fast to start with, and finishes like a machine running out of steam. A curve, the curse and the bane of watchmakers, illustrates the phenomenon: the curve of the amplitude, or angular displacement of a sprung balance wheel or a pendulum, which lessens towards the end of the run. The principle of a constant force escapement is that whatever the energy supplied by the barrel, the escapement returns a constant energy to the regulator (balance wheel). To achieve this, they had the brilliant idea of integrating an intermediate device into the escapement, consisting of an extremely thin blade that stores the energy up to an invariable threshold bordering on instability, and then transmits it allinstantaneously, before recommencing the cycle. #revolution #uhren #uhr #wriswatch #innovation #wotd #watches #watchgeek #watchporn #watchnerd #watchesofinstagram #instawatches #horlogerie #horology #swisswatch #wriststyle #luxury #luxurywatches #luxurylifestyle #hautehorlogerie #watchgame #watchaddict #reloj #relogio #escapement #constant #girardperregaux
