New Versions Of The A. Lange & Söhne Richard Lange Jumping Seconds And 1815 Tourbillon

Coinciding with Geneva Watch Days 2025, Germany’s A. Lange & Söhne introduces two new variations of existing models. We get new variations of the Richard Lange Jumping Seconds and the 1815 Tourbillon, both made in very small numbers, and both adding subtle but significant updates.

The Richard Lange Jumping Seconds comes in a pink-gold dial with a white-gold case, limited to 100 watches. Technically unchanged, it continues Lange’s foray into pink gold dials. The 1815 Tourbillon comes in platinum with a black grand-feu enamel dial, limited to 50 pieces. Let’s have a closer look!

Richard Lange Jumping Seconds

The Richard Lange Jumping Seconds puts the smallest unit of time in the largest sub-dial of a regulator layout. The seconds occupy the big sub-dial at twelve, while hours and minutes appear in smaller overlapping circles below. This regulator-style display was inspired by an 18th-century chronometer by Johann Heinrich Seyffert, a Dresden watchmaker whose work inspired Ferdinand Adolph Lange early on.

This new 2025 edition, executed in white gold, measures 39.9mm in diameter and 10.6mm in height. Its defining—and rather striking—feature is the solid pink-gold dial with black markings. This dial provides the model with a character and warmth that is unlike the existing white and black dial versions.

A complementary trio of features for Richard Lange Jumping Seconds

Inside the watch ticks the hand-wound calibre L094.1, made of 390 parts. It runs at 21,600 vibrations per hour and offers a 42-hour power reserve.

Three mechanisms work together to form a complementary trio: a constant-force escapement, the jumping seconds display, and the zero-reset system. The constant-force escapement ensures even energy delivery to the gear train while driving the second hand to jump exactly once per second. When the crown is pulled, the zero-reset function makes the seconds hand snap back to zero, enabling precise synchronization. Combined, these three features make for an exact reading of dead seconds.

Visible through the sapphire caseback, the movement shows traditional Lange details: untreated German silver plates, gold chatons held by blued screws, and a hand-engraved balance cock. The triangular indicator on the dial turns red when only ten hours of power reserve remain, signaling that the watch should be wound soon. It is such details that get our horological hearts racing.

A. Lange & Söhne 1815 Tourbillon

The 1815 Tourbillon takes a centuries-old complication and presents it in Lange’s decadent manner. Its one-minute tourbillon at six o’clock rotates to offset the effect of gravity on the balance. What sets this model apart is the addition of stop seconds and zero-reset, allowing the tourbillon cage to stop completely and the seconds hand to reset to zero when the crown is pulled. This makes accurate time setting possible, which is very rare in tourbillon watches. It does make a ton of sense, conceptually, as the Tourbillon is an accuracy-focused complication.

The case measures 39.5mm in diameter and 11.3mm in height, crafted in platinum. The jet-black grand-feu enamel dial is manufactured in-house from start to finish. The process requires more than one hundred steps and several weeks for each dial. White Arabic numerals and a railway-style minute track identify it as part of the 1815 line, linking it to 19th-century pocket watches.

The 1815 Tourbillon’s caliber L102.1

Inside ticks the hand-wound calibre L102.1, made of 262 components. It offers a 72-hour power reserve, beats at 21,600 vibrations per hour, and uses an in-house manufactured balance spring together with a screw balance.

The tourbillon is visible through the dial aperture, with its cage and bridge finished using traditional black polishing. This should guarantee some impressive light play. The three-quarter plate of untreated German silver, screwed gold chatons, and hand engraving are present as Lange’s signature movement features.

Initial impressions of these limited editions Richard Lange Jumping Seconds & 1815 Tourbillon

The Richard Lange Jumping Seconds is limited to 100 watches. It is the fourth version of the model and the fourth Lange watch with a pink-gold dial. I absolutely love this look, so keep them coming, please! The 1815 Tourbillon is limited to just 50 pieces, marking the fifth variant since the reference was introduced in 2014 and the twelfth Lange watch with an enamel dial.

I love the fact that A. Lange & Söhne puts proper thought into its concepts. It is all well and good to strive for mechanical and finishing perfection, but it only matters if those are ingredients of a concept that makes sense. This trinity of zero-reset, jumping seconds, and a constant force escapement feels clever and relevant. The same applies to the combination of Tourbillon with zero-reset and stop seconds. They are good ideas, executed to the most extreme level.

Aesthetically, both watches are vintage A. Lange, impossible to mistake for anything else. As mentioned, I like the addition of pink gold dial options to the existing offerings. At the same time, it doesn’t feel revolutionary as it is still a very classical look. All in all, these are two watches I would consider any collector lucky to have.
