WINNERL J.T.Winnerl wall-mounted
regulator, circa 1850, with one month's power reserve (engine weight muffled). White enamel dial with Roman numerals signed and numbered "WINNERL 381", two blued steel "drop" hands. The anchor of its escapement is integral with the suspension, as designed by Joseph Thaddeus Winnerl, eliminating the friction associated with the "fork" and its pivots. This anchor, in Graham's spirit for the form, is with semi-cylindrical ruby levers, called "roller" levers, perpendicular to the escapement wheel; these levers are held by a spring integral with the anchor, making it possible to avoid forcing the escapement wheel or breaking the rubies Pendulum beating the second, it is compensated nine rods with adjustment in the lens (steel and brass thermal compensation). The arm-suspension assembly of the pendulum is integral with the body. The movement is brought back after the pendulum has been placed on the stem; it is fixed on pillars integral with the stem assembly and pinned. The body is made of solid mahogany with fillets and a typical early Second Empire-style projecting lamp base. Good general condition. This Austrian timekeeper established in Paris, a pupil of A.L. Bréguet, enjoys an excellent reputation due to the high quality of his work. H. 111 - W. 34 - D. 16 cm

According to family tradition: The same regulator was made for Napoleon III and this one would come from the Duke of Morny.

A Breguet regulator that belonged to Winnerl was sold in this study on December 5, 2018

" Joseph Thaddeus WINNERL was born on January 25, 1799 in the village of Müreck, in the duchy of Steyermark, in the south of present-day Austria, not far from Slovenia. In the years 1808-1810 the family moved to Marburg, Hesse, in central Germany.
In 1823, Joseph stayed in Breslau (Prussia) and studied watchmaking. Then we find him in Altona, near Hamburg, Duchy of Holstein. There, he is taught by the watchmaker H. J. Kessels. Then he goes to Copenhagen. There he completed his training with Urban Jürgensen, who runs a watch and clock factory and acts as a State Councillor in the field of watchmaking. Then Winnerl left for Paris to join one of the greatest watchmakers of the time, Louis Antoine Breguet (1776-1858). Our Austrian settled in the capital, perhaps on July 2, 1829. He became friends with Julien Hilaire Rodanet (1810-1884), future timekeeper. Around 1829-1830 he won first prize in a competition. It was reported around 1832 at Laurette Passage (now Bara Street).
In 1831, he imagined a system of a seconds counter: the hand could be stopped and then returned to the point where it should have been if it had been left running. He then founded his own establishment.
In 1835 Winnerl was awarded the gold medal by the jury of the Encouragement Society. He is the first to manufacture chronometers in France. Winnerl creates another counter in 1840 and then specializes. In his workshop he makes chronometers or marine clocks.
He presents his work in a few memoirs. In 1844, "Modification made to the escapement has anchor for the clocks", a mechanism that reduces the number of parts and friction.
In 1844, he became a Knight of the Legion of Honour and the Société d'Encouragement published his remarks on clocks with split and split-seconds hands.
In 1847, he wrote "Reflections on the oscillations of the conical pendulum".
In 1850, Winnerl became watchmaker of the Observatory and received the rosette. Winnerl's reputation was well established: marine watchmaker, president of the Precision Watchmaking Committee, first president of the watchmakers' society founded in 1856. In 1855 he received one of the eight gold medals for watchmaking at the Universal Exhibition. He was awarded the dignity of Officer of the Legion of Honour for "the perfect execution of his chronometers".
In 1858, he developed an observation-guard counter.
In 1859, Winnerl was introduced and elected as a town councillor of Paris under Napoleon III. It will remain so until the end of the Second Empire. 2/3"
He makes the first so-called electric switch clock, placed in January 1868 in the cellars of the Observatory. The mechanism was definitively adopted for regulating clocks. Winnerl's place of business was on Avenue de l'Opéra. Winnerl sold his business to Callier in 1870. "
Winnerl dies at 87 years of age in 1886.
