WIBRAL IN WIEN.A HIGHLY IMPORTANT MUSEUM QUALITY YEAR DURATION VIENNESE WALL REGULATOR. CIRCA 1810.

An extremely important early Viennese wall regulator of one year duration. The mahogany case of a style specific to this maker has a pedimented lift off hood with ogee mouldings to the pedimented roof and very fine carcase members to the glazed front and sides. The case then has a strong under curved and chamfered moulding to the trunk of the clock which is deeper than the hood. This has a large lift out door at the front and large glass panels to both sides. The case ends with an undercut curved moulding typical of Viennese wall clocks. The whole case is extremely narrow and elegant.

The milk glass dial, signed for the maker ‘Wibral in Wien,’ has Roman numerals and finely wrought arrow shaped hands. There is a large seconds ring below 12 o’clock. The dial is enclosed within a bezel typical of Wibral with engine turning both to the front section and also a rim of engine turning on the side of the bezel. This type of bezel was almost always used by Wibral and we have only seen a similar bezel on one other makers clock.

The year duration movement has seven wheels in the train. This is an exceptionally large number of wheels in a clock train and necessitates the finest of pivots and highly accurate wheel cutting which was difficult to achieve in the early 1800s. The clock has a very delicate deadbeat pinwheel escapement. It has a metal rod pendulum which is suspended on a knife edge which is gimballed and fully adjustable and mounted on the backboard of the clock. The pendulum has a polished brass bob and rating nut.

The clock is driven by twin brass weights hanging from a yoke and pulley in a style almost always used by this maker.

Height: 55" (140 cms.)
