The Lemania 1873 is a legendary manual-winding cam-switching chronograph movement from the 1870s. Features 3-register tri-compax layout with central chronograph seconds, 30-minute counter at 3 o'clock, 12-hour totalizer at 6 o'clock, and small seconds at 9 o'clock. This movement served as the base for the famous Omega 861/863 used in the Speedmaster Professional 'Moon Watch' after the column-wheel 321 was phased out. Also used by Breitling, TAG Heuer, and Eberhard & Co. Closely related to the 1872, 1874, and 1883 variants.
