1815 Homage to Walter Lange White Gold

The A. Lange & Sohne 1815 Homage to Walter Lange was introduced in late 2017 in four metals as an ode to company (re-) founder Walter Lange, who passed away in January of the same year. It features a case of 40.5mm, which houses the hand-wound caliber L1924, with both subsidiary as well as sweep seconds hands - the latter of which can be stopped and started through the pusher at 2:00. Reference 297.0261 has a white gold case. It is a limited edition of 145 pieces, which is a reference to the years passed since the company's founding in 1845 and its re-founding in 1990.
