It was probably the precision clock of a Belgian uhrmachers, whose name stands on the dial. In this case the Lenzkirchsymbol is then milled out like nearly always. Each connoisseur will know. The Lenzkirchnummer, approx.. 370,000, is however present. Like that is the clock on approx.. to date 1866 The clockwork is functional! Must be cleaned. The dial is immaculate. High-quality genuine kompensationspendel! The height is 2.05 meters. See book of "Lenzkircher Uhren" S. 109.
