An extremally rare and unusual Laterndluhr. The case of very light coloured mahogany is strung with a darker wood. It is of typical form with a pedimented top with opening door which slides off, and lift out doors to the trunk and base of the clock.

The dial of the clock is its most unusual feature and is particularly attractive. I have not seen a similar dial in 50 years of collecting and dealing. It has a gilded centre with an enamel outer chapter ring with Arabic numerals for the minutes. There is a subsidiary enamel dial at the bottom of the centre with Roman numerals for the hours. At the top there is a half round enamel dial with the days of the month. This is for the fly back calendar. It has nicely shaped blued steel hands, and is signed for the maker Joseph Felz in Wien. It is nice that the signature and numerals on the dials are fired in rather than the more normal Viennese process of painting them on.  The dial is surrounded by a gilded engine turned bezel.

The steel rod pendulum has a brass bob and is knife edge suspended from the backboard. The month duration weight driven movement has a deadbeat escapement, maintaining power and the most unusual feature of the fly back calendar. This is achieved with a main pinned calendar wheel which is weighted on one side. When the calendar has clicked over to 31 days on its next click it moves to a position where the wheel is free to run and it therefore falls back due to the weight on one quarter of the wheel, and then locks in at day one. After that the process starts all over again. It has nicely shaped and adorned pillars, and the usual fine quality wheel work.

Length: 42″ (107 cm)

The maker Josef Felz is noted as a Master in the country in 1811 . From 1811 to 1827 he is noted as a Guild Member, this suggests that was when he moved to Vienna.
