An exceptional Viennese mahogany longcase clock. The beautifully figured mahogany case has a lift off hood in the style of a Laterndluhr with profuse edge stringing to the pediment, the door and the glass apertures. It then comes down through a complex moulding, again edge strung throughout, into the trunk of the clock. This has a Laterndluhr style lift out front door and has scroll topped slightly tapered side pieces which give a wonderful proportion to the case. The scroll tops have nicely turned end caps with light wooden ball shaped centres. Again the signed apertures and the tapered side pieces are edge strung with maple wood.

The clock then goes out into a fully panelled base which has superbly chosen flame veneers and canted edging to the inset panel. The edges of the panel are also line inlaid with maplewood. The clock then stands on an ogee moulded plinth quite significantly larger than the base in order to give it stability. As with all Viennese floor standing clocks, the clock is provided with a hanging bracket on the backboard and has case stabilizers. This means that the clock would normally be hung from the wall with the base just brushing the floor. The case is very thin to the wall, only some 6″ deep at the trunk and hood.

The dial of the clock is particularly attractive. It has a beautiful large engine turned and fire gilded outer bezel and an engine turned and gilded inner bezel. The silvered brass chapter ring has Roman numerals with a minute ring outside and the centre of the dial is beautifully engraved with a signature panel signed for the maker ‘F M Rannar, Wien’ and a seconds ring below XII. The blued steel hands are very finely fretted and the minute hand is counter balanced. They are of beetle and poker type, but with cross pieces.

The year duration weight driven movement is of three plate construction. It has a large great wheel with a relatively long and thin barrel which goes between the backplate and the main front plate. The other four wheels in the train are pivoted between the backplate and a third plate with a very tiny separation. This is to stop any flexing in the higher wheels which can occur in long duration clocks because of the large driving weight. The pillars of the clock are nicely turned with knurled adornments in the middle. The pillars are replicated on the large brass mounting plate which is fixed to the backboard and onto which the movement latches with keyhole slots. The clock has very fine wheel work and in particular the great wheel has in excess of 200 teeth. The clock has maintaining power, a Graham deadbeat escapement and end stops throughout the train. The heavy brass bobbed pendulum has a wood rod and is suspended from the movement mounting plate of the backboard. There is beat adjustment at the bottom of the crutch where it goes into the pendulum. The clock runs on a brass cased weight with a blued steel hook and mounting washer at the top. The weight, although heavy, is about the same size as you would find on a month duration English longcase clock. The pendulum runs against a silvered beat plaque mounted on the backboard and the weight goes through a square aperture cut in the baseboard of the clock at the bottom of the trunk. This gives the longer drop into the base of the clock in order to get the year duration.
