DateCirca 1835
A fine mahogany cased six month duration laterndluhr by this eminent imperial clockmaker.

A rare and imposing mahogany cased Laterndluhr. The case with very finely figured mahogany veneers. It has the usual lift off hood with opening door and two lift out doors to the centre and bottom of the case. All of the glass apertures and top and bottom of the hood are nicely strung with boxwood. The clock has its normal under curved base with two stabilizing screws to the sides.

The large 11 inch white enamel dial is signed for the maker Marenzeller in Wien and has a seconds hand below XII and nicely shaped blued steel hour and minute hands. It has a wide gilded bezel with fine engine turning.

The movement is the clock’s finest feature. It has five wheels in the train, together with a very small diameter main barrel which protrudes out of the back of the movement. This enables it to have its six months duration. The plate separation is extremely narrow which is done to avoid flexing of the arbors when using a heavy weight for long duration. The wheel work is of the usual fine quality and the clock has end stops throughout the train, together with full glass enclosure to the movement to keep any dust out from the workings. The deadbeat escapement has depthing adjustment via a screw on the back cock and the pendulum has a regulator style suspension spring mounting. There is beat adjustment on the end of the crutch with the unusual feature of a square end to the adjustment arbor which is adjusted via a long purpose built key to enable easier adjustment from the side of the movement. The whole movement is of the finest quality.

The heavy wood rod pendulum has a nicely turned and embellished adjusting nut and a blued steel pointer. The large brass cased weight is off set and runs down behind the pendulum.

Height: 57 in (145 cm.)

* The maker Ignaz Marenzeller was born in 1797 and died in 1877. He became a Master Clockmaker in 1831 and is noted as being a Royal/Imperial Clockmaker. This means that he would have made some clocks for the Imperial Family and perhaps was involved in repairs and restorations for them. Only the finest clockmakers had this accolade.
