The Richard Lange Jumping Seconds was a surprise hit when A. Lange & Söhne unveiled it at SIHH last year. Powered by the newly developed cal. L094.1, the watch was platinum, 39.9mm in diameter and told the time with a formal yet rigorously beautiful regulator-style display. Now Lange has unveiled a sumptuous pink gold version.

The dial remains the same: characterised by three intersecting off-centre subdials inspired by  the famous no. 93 regulator pocket watch created in 1807 by Dresden royal watchmaker Johann Heinrich Seyffert. This is the same dial that inspired the earlier Richard Lange Tourbillon Pour le Mérite and Perpetual Calendar Terraluna.

The only changes on the pink gold model are the hour and minute hands, now in pink gold, complementing the red quarter minute numerals. Apart from the case material and hands, everything else about the watch remains identical to the platinum version.

Just under 12 o’clock there’s a small triangle for the power reserve indication which gradually changes from white to red as the mainspring winds down.

And the highlight of the movement is the jumping seconds complication, displayed on the largest sub-dial with a blued steel hand. Unlike many of deadbeat seconds, this is linked to a constant force mechanism.

Specifically, the movement is equipped with a remontoir on the fourth wheel. It’s a tiny spring that equalises torque from the mainspring throughout the course of its 42-hour power reserve. The spring remontoir is re-wound once per second, and its forward jump then propels the seconds hand. This can be witnessed through an aperture on the three-quarter plate where the remontoire is disengaged for rewinding every second via a star wheel on the escape pivot.

The zero-reset seconds mechanism to the left, beside Lange’s signature engraved balance cock.

The jumping seconds is enhanced by Lange’s patented Zero-Reset mechanism. A vertical clutch separates the fourth wheel from the rest of the going train, so when the crown is pulled out, the seconds hand jumps to 12 o’clock, facilitating precise time synchronisation.
