These representative clocks are defined by using materials of the highest quality and a precise manufacturing. A grate dial of care is devoted to each clock and each clock is a unique original. Designing our clocks we place a great emphasis on a minimal amount of maintenance clocks will require in the future.
As a basic model for our clocks we took clocks from 19th and 20th century. Unlike these machines, ETALON clocks have extended length of running time to one month which makes the maintenance much more comfortable. Another significant change is inverted Graham deadbeat escapement – similar to Strasser and Rhode concept - which is visibly located under the dial. Each clock case is unique in its design and type of wood used.
