NIELSEN LEMVIG / 1893' and inscribed 'KRONO METER', the twin train brass movement with shaped triangular plates, deadbeat escapement and replaceable screwed bushes, the large pendulum with steel  / nickel rod and solid brass bob, with brass and silvered compensation indicator to the top signed 'P.

His clocks are located in both Danish and US collections. This precision pendulum clock was designed and produced from handmade, non-prefabricated parts produced by Nielsen himself. Nielsen is perhaps best known for the early automobile that he built in 1906 in Lemvig, which was particularly notable because of the gear system.
