A Lange 1815 Up-Down Ref 234 Series

A. Lange & Sohne debuts its new 1815 UP/DOWN in 2013.  Available in your choice of 39mm x 8.7mm pink/yellow/white gold case , this is a simple and elegant watch with power reserve indicator (“UP/DOWN” aka “AUF/AB”) situated lower left and small seconds subsidiary dial on the lower right.  Historically speaking, the brand’s iconic UP/DOWN power-reserve indicator was first used in historic pocket watches and marine chronometers dating back to a Lange patent granted in 1879.  More looks below.

The sweep hour and minute hands as well as the hands of both subsidiary dials are made of blued steel – a typical design feature of earlier Lange pocket watches, just like the recessed central segment, the Arabic numerals, and the railway-track minute scale.
