AI-CAT170-29 Niello The niello watch case became a canvas for outstanding art works that will likely never be duplicated. The term niello comes from the Latin word nigellum that is the diminutive of niger (black.) It was a technique used by the ancient Greeks, Romans, Egyptians and Persians. Niello is a black or blackish-blue composition of lead, silver, copper, sulfur and ammonium chloride. The mixture is fused onto an engraved or cut-out metal base by firing the mix in a process similar to champleve' enameling. Silver was the most often used metal for niello objects since the soft white silver color contrasted beautifully with the darker niello. Rose-gold inlay work was also seen in combination with niello and tri-color effects were achieved by the use of rose-gold, niello and silver. When the niello was heated and fired onto a silver watch case, it actually fused with the silver very strongly, almost as if it were soldered in place. The niello would be filled, finished and polished, leaving the surface of the watch case smooth and flat. One can readily assume that the process of engraving the areas which were to be filled with niello, the firing stages, and the finishing stages were very time consuming and therefore costly. Aside from the production end, the niello cases also had to be designed by artists who would pre-determine the subject matter and then the cases were finished by engravers who produced the fine details. Lever Escapement An escapement is a device in mechanical watches and clocks that transfers energy to the timekeeping element (the "impulse action") and allows the number of its oscillations to be counted (the "locking action"). The impulse action transfers energy to the clock's timekeeping element (usually a pendulum or balance wheel) to replace the energy lost to friction during its cycle and keep the timekeeper oscillating. The escapement is driven by force from a coiled spring or a suspended weight, transmitted through the timepiece's gear train. Each swing of the pendulum or balance wheel releases a tooth of the escapement's escape wheel gear, allowing the clock's gear train to advance or "escape" by a fixed amount. This regular periodic advancement moves the clock's hands forward at a steady rate. At the same time the tooth gives the timekeeping element a push, before another tooth catches on the escapement's pallet, returning the escapement to its "locked" state. The sudden stopping of the escapement's tooth is what generates the characteristic "ticking" sound heard in operating mechanical clocks and watches. Full Plate A plate (or disc) that covers the works and supports the wheels pivots. There is a top plate, a bottom plate, half, and 3/4 plate. The top plate has the balance resting on it.
