Telechron Model 4H77 "Deauville"

The Telechron model 4H77 "Deauville" was available either in blue mirrored glass with a blue face, or this version, with black Carrara glass.  It was sold between 1937 and 1939.  A similar clock, the Statesman, had a white onyx case.  The Deaville stands about 7 inches high, and is 6 inches wide.  The metal parts are lacquered brass.

Carrara glass was made by the Penn-American Plate Glass Company and was used extensively during the 1920's and 30's Art Deco and Streamline eras as an architectural element.  It provided an extremely dark black surface that also had a very smooth, reflective surface, and was used as an inexpensive substitute for genuine marble.  Carrara glass was, in fact, not black but was a deep red or green color, with a coating of black paint on the back side.  As such, it was probably cheaper to manufacture than actual black glass.
