722.050

The ref. 722.050 Lange 1 Tourbillon was introduced in 2010 in celebration of the 165th anniversary of the A. Lange & Söhne founder's move to Glashütte - ehm, yes. It was a limited edition of 150 pieces and the first 50 pieces were sold in a set with the 712.050 and 212.050. The case is done in Lange's proprietary 'Honey Gold'.
