Joseph Thaddäus Winnerl, No. 381, Height 1110 mm, circa 1850
An important precision regulator with grid iron and brass pendulum and pendulum lever with spring impulse escapement
Case: mahogany. Dial: enamel. Movm.: circular brass plate movement, lateral weight driven, lever with ruby paletts, pendulum spring suspension.
In the order of things, this spring detent escapement by Josef Thaddäus Winnerl lies between the escapement developed by Friedrich Tiede (such as described by Jürgen Ermert on page 221 of volume four of his series of books on precision pendulum clocks) and the Riefler escapement invented by Sigmund Riefler. The spring arms are tightly connected to the pendulum through the suspension and end in two ruby pallets which engage with the gear wheel and are thus driven by it. Even the supports which the springs are fixed on with a pin are fitted with rubies. (A similar movement by Winnerl is illustrated and described in: "Präzisionspendeluhren" (precision pendulum clocks) by Erbrich, p. 199.) The circular movement has a diameter of 119 mm and sits in a brass casing. Anchor and design of the movement are reminiscent of the pendulum clock by Auguste Fénon we presented during our 93rd auction; Fénon supplied many French observatories with precision pendulum clocks and trained with Winnerl in Paris. Unlike the stark design of the observatory clocks, however, this is a pendulum clock that strikes 80 times per minute and sits in a magnificent mahogany case with a lateral weight designed to match the outline of the case. It is alleged that Winnerl created an identical model for Napoleon III; this clock is said to have been owned by half brother, the Duke of Morny.
Joseph Thaddaeus Winnerl (died 1886) was born in Austria (Styria) in 1799. From 1829 he lived and worked in Paris, where amongst other constructions he designed a split second mechanism for chronographs. In 1839 Winnerl won gold medal in Paris. He was an excellent maker of chronometers and balances and even invented his own compensation balance. Ferdinand Adolf Lange worked for him until 1842.
