A. Lange & Söhne Lange 1 191.032

The case measures 38.5mm across and 9.8mm thick. Case material: 18k white gold. Case size alone is a poor guide to how a watch wears; lug-to-lug length and how the bracelet drops off the case matter more, which is why we suggest trying one on before you commit.

Manual wind, Lange Cal. L121.1, in-house, hand-finished. Power reserve is 72 hours. It beats at 21,600 vph. The movement uses 43 jewels.

It is rated to 30 meters, about 98 feet. That covers rain and hand washing. It is not rated for swimming. One caution that applies to every watch on this page: a water resistance figure describes a new watch with fresh gaskets. On a piece that is years past its last service, treat the rating as unknown until it has been pressure tested.

A. Lange & Söhne produced this reference from 2021 to the present day. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.

191 = current-generation Lange 1;.032 = white-gold case with argenté (silver) dial. Reading the reference is the fastest way to confirm that a watch is what the seller says it is, before you get anywhere near the movement.

Lange 1 (current/2021+ generation), white gold, argenté dial. Collector nicknames are not official A. Lange & Söhne names, but they are what people actually search for and what they are called across a showroom.
