Identity and Attribution
This longcase clock is catalogued under maker Adolf Loos and dated to circa 1904. The catalogue designates it as 'PROPERTY FROM A DISTINGUISHED PRIVATE COLLECTION' under lot 51. The auction entry records that the case was 'likely executed by Johannes Heeg, Vienna, Austria', expressing a qualified rather than certain workshop attribution for the physical fabrication of the case.
Dial and Visible Movement Components
Visible within the upper section of the vitrine is a circular clock dial exhibiting an iridescent patina and dark Arabic numerals. Observation of the interior reveals a visible central pendulum with an elongated rod and large circular bob, alongside a suspended cylindrical weight hung from a pulley positioned behind the pendulum rod.
Case Design and Glazed Vitrine Structure
The clock is documented with materials of copper-plated brass, glass, and brass, measuring 130 x 41.5 x 26.6 cm (51 1/8 x 16 3/8 x 10 1/2 in.). Direct visual observation confirms a full-height transparent glass vitrine casing with copper-plated brass framing, elevated upon four low corner feet supporting the brass base.
