With copies of the Geneva Observatory timing sheet and results of the 1918 timing contest where the watch obtained 362 points.
The present is a highly unusual and elaborate example of a presumably school watch, made by Emile Richon, student at the Geneva horological school from 1913 to 1918, most probably the watch he presented when graduating from the celebrated institute.
Few information is available about Emile Richon but he unquestionably was a highly talented watchmaker. His drawing of a chronograph movement with counter, obviously the design for the present movement, can be found in La Chaux-de-Fonds celebrated Musée d'Horlogerie. The latter also owns a regulator clock by Emile Richon as well as other drawings and his Certificate of Geneva's Horological School dated 1917.
The Swiss Horological Federation magazine, edition no. 15 dated 23 February 1918, publishes under "1917 Chronometer Contest at the Geneva Observatory" the relevant results, including the "Prize for the first bulletin in the 1st class contest", awarded to the precision adjuster Richon, student of the Ecole d'Horlogerie.
Emile Richon's masterwork combines, in addition to its exceptional quality and craftsmanship, an impressive number of features such as a chronometer movement awarded an Observatory Bulletin and stamped with the Geneva seal, a chronograph with 30 minutes counter based on his design, a finely engraved gold dial and last but not least a sumptuous champlevé and cloisonné enamel decorated case, all rarities by themselves.
Obviously hardly used and preserved in excellent overall condition, the present watch represents a rare find for the amateur of unusual timepieces of highest quality.
The Geneva Seal
The Geneva Seal, perhaps the most stringent set of rules ever established for any manufactured product, was created in 1886 by an institution called "Poinçon de Genève" (Geneva Seal) to classify timepieces built following Geneva's traditional watchmaking standards. It is exclusively applied to locally-made mechanical movements which comply with the highest quality criteria. Still today the Poinçon de Genève sets the most demanding standards for watchmaking anywhere in the world.
