A Dutch Art Deco ‘Amsterdamse school’ copper mantel clock, Winkelman & Van der Bijl, circa 1920.
The painted dial has stylized Arabic numerals around a sunburst. The shaped hands are made of iron.
The movement is driven by two spring barrels and has a duration of eight days. It is regulated by anchor escapement in combination with a pendulum. The clock strikes the hours and half hours on a bell by means of a countwheel.
The shaped case is made of hammered copper. The bottom has two shallow arches connecting in the centre. The whole is placed on feet with vertical incised lines.
