A. Lange & Söhne introduced the Richard Lange Jumping Seconds watch at SIHH 2016, solely in a platinum case. The Saxon brand follows it up this year with a brand-new version of the popular timepiece in rose gold and, like its predecessor, strictly limited to 100 pieces.
The A. Lange & Söhne Richard Lange Jumping Seconds garnered watch-world acclaim for its combination of two complementary mechanisms: a one-second constant force escapement and an integrated jumping seconds function that displays the precise time in crisp, one-second intervals.
