In the era when the smallest unit of time were seconds, not tenths of a second, those days of royal and imperial monarchy of Josef II., the great Viennese Art of Clockmaking was established. Driven by the commercial promotions of the monarch the clockmakers were able to defy in technical as artistic manner with the other major european metropols of clockmaking, London and Paris. From the perspective of the collector, this is significant because in general collecting and rating is done by manufacturers, according to provenance.
Therefor the area of colleting is regional, as opposed to other collection areas. This means that the domestic market is always the most significant market for collectors. The exchange between areas or cities is estimated as rather low. This is also because tastes and interior conditions prevented nearly a lively exchange.
There can be named two criterias of the collecting area. First, collecting according to technical and second according to stylistic criterias. From the technical perspective this makes sense when cherishing clocks before 1860. Around the year 1860, parallel to the development of automatic machines, mechanical clock movements production became even more mass-produced and more alike. With the turn of the century there were hardly any regional differences in the movements, because the movements were distributed “large scale”. Special feature of the great Viennese clocks were the “Viennese Stroke” also called “Great Sonnerie” in the clockmaking world. At every quarter-hour a sound with the number of quarter-hours is played on gong or bells. On the hour this stroke is accompanied with a second different stroke. With an special repeater mechanism this stroke can be played again to strike the current hour. In the technical clockmaking language this function is also compared to “Night Watches”
This magnificent chiming Skeleton Clock is the result of months of painstaking hand work. Each plate is individually cut out of solid brass, edge filed, papered smooth, burnished and gilded before finally being built into a finished clock. Every wheel and arbor, detent and lever has been finished by hand to give the whole mechanism the glittering aspect of a true work of art.
This elegant Skeleton clock with a novel pendulum arrangement features a dramatic hand painted Sun and Moon dial. The dial rotates once a day revealing a Day and Night sky into which is incorporated a Moonphase aperture showing the different phases of the moon throughout the 29 ½ day cycle.

The precision pendulum clock GRAMAT is the only clock currently being produced that operates in a partial vacuum similarly to the clocks in evacuated tanks produced in the last century. After a long development period, PW has succeeded in producing hand-made, extremely delicate and airtight housings. By means of a patented process, the density of the enclosed air is kept remarkably constant, thus protecting the pendulum from atmospheric changes. The sensor is a glass ball with a volume of approx. one liter. The air’s density affects the ball’s buoyancy, which, in turn, controls a small vacuum pump located in the base of the clock. This control mechanism is so sensitive that it is triggered by density changes of less than 0.1 mg per liter, which corresponds to a change in air pressure of 1/10 hPa. The control panel is located in a drawer. When it is time to wind up the clock, the vacuum control unit is turned off and air is permitted to enter through a valve. The air pressure is indicated on a precise diaphragm pressure gauge.
