** Richard Lange Jumping Seconds** is a luxury wristwatch by [[A. Lange & Söhne]].

The watch attracts attention by the unusual arrangement of hands on the dial. The representation of the time units with three overlapping displays goes back to the Dresden astronomer and watchmaker Johann Heinrich Seyffert. His famous pocket chronometer No. 93 from [[1807]] was the first watch with such an arrangement.

The [[Lange L094|L094.1]] movement features the elaborate [[complication]] of [[jumping seconds]] with [[hacking seconds]], combined with a [[remontoire]]-[[constant force]] mechanism.

The platinum model was introduced [[2016]], the red gold model [[2017]] and the white gold model [[2019]].
