Glass mantel clock by ATO, 1930

ATO: a stylish Art Deco glass mantel clock by the French firm ATO. Unusual in its design as the Art Deco numerals are pierced out in frosted glass, and set against a pale pink-tinted mirrored face and black Bakelite base. French, circa 1930.

Height: 8 inches (20 cm).

ATO was established in the 1920s by Léon Hatot (1883-1953). Trading under the name ATO from 1923, electric clocks were produced in a partially rebuilt factory in Besancon, France. They were an immediate and unprecedented success, and at the Exposition Internationale des Arts Décoratifs in 1925, Léon Hatot won the Grand Prix for a range of electric clocks, housed in marble, chrome and fine wood cases, and some in cases of moulded glass from the famous Lalique factory. Léon Hatot’s company still exists as part of the Swatch group.
