Lot Essay

1815 is a model specifically designed by A. Lange & Söhne made in honour of Ferdinand A. Lange, who was born in 1815. He is the founding father of not only the brand but also the precision watchmaking industry of Saxony, Germany.

The challenge in creating this watch is the combination of two of the most popular complications among watch connoisseurs - the perpetual calendar and the split-second chronograph, while keeping the watch structured in a sizable manner. Another remarkable feature of the movement is the usage of its two column wheel chronograph mechanism for both its chronograph hands. Creating such a mechanism is very labour intensive but it enables the pusher action to run smoothly in comparison to other chronograph watches.

Not only is this watch aesthetically pleasing because of its classically beautiful dial with blue hands, it is also well-crafted and displays perfection in the art of Saxony watchmaking.
