A mechanical chronometer is a spring-driven escapement timekeeper, like a watch, but its parts are more massively built. Changes in the elasticity of the balance spring caused by variations in temperature are compensated for by devices built into it. [2] Chronometers often included other innovations to increase their efficiency and precision.
The hand-winding movement of a Russian watch. A mechanical watch is a watch that uses a clockwork mechanism to measure the passage of time, as opposed to quartz watches which function using the vibration modes of a piezoelectric quartz tuning fork, or radio watches, which are quartz watches synchronized to an atomic clock via radio waves.
Marine chronometers always contain a maintaining power which keeps the chronometer going while it is being wound, and a power reserve indicator to show how long the chronometer will continue to run without being wound. These technical provisions usually yield timekeeping in mechanical marine chronometers accurate to within 0.5 second per day ...
This being the case, the totality of the checks (magnetism, operation, and water resistance) guarantees a very high-quality mechanical watch for the end customer. Mechanical watches can be first COSC ISO 3159 "Chronometer" certified and after that METAS N001 "Master Chronometer" certified when all the relevant requirements are met. The first ...
Where "Chronograph" refers to the function of a watch, chronometer is a measure of how well a given mechanical timepiece performs: in order to be labeled a chronometer the timepiece must be certified by the COSC, the official Swiss Chronometer testing institute, [20] after undergoing a series of rigorous tests for robustness, accuracy and ...
