This non-working Vallon pocket watch has several engravings. On the sides it has diamonds and flowers. On the back there is a steam locomotive on what may be a brick overpass. Inside is the most interesting: while it is engraved "Cylindre" (movement I believe) and "10 Rubis" (10 jewels, the more interesting engraving is the "Sauser" and "Chaux de Fonds" engraving. There is a famous Swiss born novelist named Frederic Sauser (AKA Blaise Cendras) who lived in Chaux De Fonds Switzerland. He also started out as a watchmaker. It's possible this watch was made for him, made by him, given to him by his watchmaking mentor, given to hi m by the town he lived in--Chaux De Fonds. Saucer was a very good friend and from the same town as famous artist, architect Le Corbusier.
Purchased from classified paper seller about 30 years ago who had it in a box of old watches.
Thanks for your request. This is a pocket watch made by the workshop Vallon located in the village of Chaux de Fonds in the famous watchmaker area of Neuchâtel in Switzerland. Regarding to the style of the decor, it was made in the second half of the 19th ct. probably shortly before 1900. The case is probably made out of silver and the clockwork is not working anymore. There is also an engraving of a locomotive on the case. Without knowing how serious the damage of the clockwork is, a low estimation is more appropriate. An estimation would be then from 50 to 100 USD.
With best regards,
