Record status

Individual type · partial

Period

circa 1900

This early table clock, designed circa 1900 by Austrian architect Adolf Loos, features a glazed rectangular housing with canted interior corners and beveled crystal panels on all sides.

Fabricated from copper-plated brass, brass, and steel, the structure stands on diagonally oriented faceted crystal-form feet. Its suspended circular dial presents Arabic numerals and blued spade hands positioned above an exposed pendulum bob. The auction catalogue notes the case was probably produced by Viennese metalworker Johannes Heeg, and the reverse of the dial is painted with a later notation dated December 15, 1911.

Design

Visible features
• Glazed rectangular brass-finish case with beveled crystal panels on all sides • Internal frame corners are canted • Circular metal dial displaying Arabic numerals and blued spade hands • Visible circular pendulum bob suspended below the dial • Four diagonally oriented faceted crystal-form metal feet supporting the stepped plinth base
Construction and Features
The clock features a stepped plinth base supported by four diagonally oriented, faceted crystal-form metal feet. The internal frame is characterized by canted corners. The clock includes a circular metal dial with Arabic numerals and blued spade hands. A circular pendulum bob is suspended below the dial, which is fixed to the rear glass.
Attribution and Provenance
The case is attributed to Viennese metalworker Johannes Heeg. Documentation notes that Heeg produced some of Loos’s cases, though it is not confirmed if he produced all of them as he did not sign his work. The clock is provided with a double-end case and a clock key.
Object Description and Dating
This table clock is designed by Austrian architect Adolf Loos. The housing is rectangular, fabricated from copper-plated brass, brass, and steel, with beveled crystal panels on all sides. The rectangular case design with canted corners indicates it is a model produced before 1906. Based on the face and dimensions, the source suggests a date of circa 1900. The reverse of the face bears a painted notation dated December 15, 1911.
