A. Lange & Söhne 1815 Up/Down: Blue-Dial Compact Editions Debut at Concours of Elegance

Hampton Court Palace on a September morning is not the usual setting for a German watch launch, but that is exactly where A. Lange & Söhne chose to unveil its first new watches of the autumn: a pair of 1815 Up/Down special editions that shrink the collection’s signature power-reserve watch to a compact 37.5mm and colour its dial deep blue. Presented over the Concours of Elegance weekend, the two references — 244.028 in 18-carat white gold and 244.037 in 18-carat pink gold — are each limited to 300 pieces, and both lean into the dress-watch downsizing that has reshaped the top end of the market over the past two seasons.

In the metal, the first impression is how much of the 1815’s personality survives the reduction. The railway-track minute scale, the recessed centre of the dial, the Arabic numerals and the off-centre sub-dial arrangement all carry over unchanged from the 39mm Up/Down. What is new is the dial itself: a blue surface in 925 silver, with twin argenté sub-dials sitting at 4 and 8 o’clock. On the white-gold reference the combination reads almost achromatic and crisp; on the pink-gold version the blue warms against the rose case. It is the kind of colourwork Lange has been adding selectively to its classics, and here it gives a very traditional time-only layout a contemporary edge.

A Smaller Stage for the AB/AUF Indicator

The 1815 Up/Down takes its name from the one complication it exists to show off. The “AB” (abgelaufen, or down) marker at the bottom of the power-reserve arc represents a fully unwound mainspring, while “AUF” (aufgezogen, or up) indicates a full wind — a display with deep roots in Saxon pocket watchmaking, where knowing how much run time remained was a practical necessity. Unlike many brands that bolt a power-reserve module onto an existing movement, Lange integrated this one directly into the calibre using a space-saving planetary gear system, so the indicator reads the true state of the mainspring rather than a separate train.

The arc at 8 o’clock carries a red segment warning that only six hours of the 72-hour reserve remain. It is a small, humane touch: glance at the dial and you know whether the watch needs winding before you leave the house, no guesswork required. Opposite it, the subsidiary seconds at 4 o’clock uses blued-steel hands, while the central hour and minute hands are lancet-shaped and finished to match the case metal — white gold on the white-gold watch, pink gold on the pink-gold version.

Inside the L051.2

Flip either watch over and the caseback sapphire reveals the manually wound L051.2 manufacture calibre, and this is where Lange’s hand-finishing argument gets made in full. The three-quarter plate is untreated German silver, which slowly takes on a warm patina over years of wear; the winding wheels visible through the plate carry solarisation; and seven gold chatons, each secured by a blued screw, hold the jewels in place. Underneath the hand-engraved balance cock sits a classic screw balance with an indexless regulation system and a Lange balance spring made in-house. It runs at 21,600 vph (3Hz) and offers 72 hours of power reserve from a single barrel, with 245 components in total.

White Gold or Pink Gold: Two Readings of One Watch

The two metals are more than a cosmetic choice. The white-gold 244.028 pairs its blue dial with a blue alligator leather strap, creating a cool, monochrome silhouette that disappears into a cuff and reads as the more discreet of the pair. The pink-gold 244.037, by contrast, is worn on a reddish-brown alligator strap, and the warmth of the case colour gives the blue dial a glow the white-gold version simply cannot match. Both close with matching gold pin buckles, and both stop at a remarkably slim 8.7mm in height with a 45mm lug-to-lug, which is what makes a 37.5mm case wear as elegantly as it does on the wrist.

Lange Returns to 37.5mm

This is not the first time the 1815 Up/Down has been built at this size. Back in 2006, Lange produced a limited run of the same watch in 37.5mm as a tribute to Walter Lange, using a case diameter that was already considered small for a men’s watch at the time. Eighteen years on, the industry has caught up with that instinct — 37mm to 38mm has become the sweet spot for dress pieces, and Lange’s decision to revive the dimension for a regular (if limited) production run feels less like nostalgia and more like a statement of where the category is heading. The compact case also keeps the overall weight down despite the precious-metal construction, which was immediately noticeable when handling both references side by side.

Availability and Pricing

Both new 1815 Up/Down references went on display at the Concours of Elegance, which ran from 4 to 6 September at Hampton Court Palace, and they are now in the hands of Lange’s global boutique network. As with most of the manufacture’s current output, pricing is on request, though the outgoing 39mm models sit in the €40,000 range across Europe; trade press reports put the new blue-dial editions at approximately €45,000. Each reference is strictly limited to 300 numbered pieces, with the edition number engraved on the rim of the caseback.

Lange & Söhne. Full details of both references are available on the official A. Lange & Söhne product page, and the brand’s press release for the 1815 Up/Down documents the full background of the launch.
