Escapement Energy from the mainspring is restrained by the escapement to help control the gear train. At the same time the escapement provides further energy to the balance spring where unavoidable losses due to friction are compensated. Contemporary wristwatches usually contain the pallet escapement which consists of the escapement wheel and its pinion. Faraday cage A unique mechanism developed by Bremont consisting of a soft-iron housing in which the movement is cushioned, routing magnetic fields around the movement. Flyback The Flyback function allows an ongoing time measurement to be interrupted and a new one to be started instantaneously by merely pressing a button. It combines three steps – stop, reset to zero and restart – into one. In chronographs without the Flyback function, these three steps must be executed consecutively. This function was originally invented in the early

B-EBE2000 This is a special stage in the case production, in which the metal is bombarded with electrons to give the stainless steel a dramatically increased hardness and scratch resistance. On the Vickers scale of hardness, B-EBE2000 produces a watch case with a value of 2000, which is approximately seven times that of the normal stainless steel used for watch cases. Calibre A term used to describe the form and/or size of a movement and often specifying the type of movement. Chronograph A watch with a stopwatch mechanism. Chronometer A chronometer defines the accuracy and testing over an official 15-day series of tests by the official Swiss Chronometer testing institute, over a range of temperatures and five physical positions. The average daily deviation rate of the movement must be between –4/+6 seconds per day and only then can the movement be awarded as a chronometer and ultimately receive a certificate issued by the COSC. C.O.S.C (Right) Contrôle Officiel des Chronomètres is an independent, non-profit, testing body for watches manufactured in Switzerland to defined accuracies. DLC Black Diamond-Like Coated hardened stainless steel. Domed crystal A convex pane of clear glass-like material (usually artificial sapphire) covering a watch’s dial.
