287-4220 Wall clock: significant precision second-pendulum clock, circa 1875, J. Wirén, St Petersburg/presumably Pulkovo Observatory
Case ca. 150 x 40 cm, brass/wood with glazed front, heavy brass suspension, precision lever movement with heavy seconds pendulum and fine adjustment, Graham escapement, weight drive, signed regulator dial, intact. Johan Wirén was a renowned mechanic and clockmaker in St Petersburg, best known for his astronomical and scientific precision instruments. His second-pendulum clocks were often used as time standards in observatories, institutes or for maritime purposes, as they exhibited extremely high accuracy. Wirén worked during an era when St Petersburg was a centre for precision engineering within the Russian Empire. His workshop supplied instruments that could compete in quality with the major European manufacturers such as Riefler or Strasser & Rohde. (Source: German Society for Chronometry e.V.). "Wirén, Johan, born in 1835 near Helsinki, died in 1885 in St Petersburg, where he also lived and worked. Following Pihl’s death in 1873, Wirén took over the position of Master Chronometrist at the Imperial Pulkovo Observatory near St Petersburg.
