A. Lange & Söhne Datograph Perpetual 410.136E Marks 20 Years in Platinum

Time on the Move | By Zach Charles| Published October 29, 2026 | Limited Edition

The A. Lange & Söhne Datograph Perpetual ref. 410.136E, announced around October 24, 2026, marks 20 years since Lange introduced the model in 2006. It is a 950 platinum watch on a new five-row platinum bracelet, with a black solid-silver dial and eleven baguette-cut diamonds in place of the usual hour markers. Production is limited to 50 pieces and Lange has not published a price. The mechanics are unchanged: manual-winding calibre L952.1 with a flyback chronograph, perpetual calendar and outsize date. This article rests on trade coverage; Lange's own page returned an error when we tried to read it.

What the Datograph Perpetual 410.136E changes

Almost nothing in the mechanism. The case measures 41mm across and 13.5mm high in 950 platinum, and SJX says it is unchanged from the 2006 original, with much of the height coming from the domed bezel. The calibre is the same L952.1 family, and the 36-hour power reserve is unchanged, which SJX flags as a modest figure for a perpetual calendar.

The changes are visual. Luxe Digital calls this the first black dial on a standard Datograph Perpetual, while SJX describes black paired with silver registers as a combination earlier versions did not offer. Where previous watches had baton hour markers, this one has eleven baguette-cut diamonds, graded F-G in colour and VVS in clarity according to Time and Watches. There is a pair at 12 o’clock and none at 4 and 8, where the sub-dials sit.

Our reading, not Lange’s statement: the watch is a dress-up of a proven design for collectors who already know the model, rather than a technical step. SJX reaches a similar conclusion, calling the changes cosmetic and the update a strong one.

The platinum bracelet

The bracelet is the main news. It has five rows of links with chamfered edges and alternating polished and matte surfaces, ending in a platinum deployant clasp. Time and Watches describes it as integrated into the case. Luxe Digital, Gear Patrol and Monochrome say it was designed in-house and is not the work of Wellendorff, the German jeweller whose metal bracelets were fitted to earlier Lange watches.

Sources differ on its design lineage. Revolution says the links are squarer than the original’s and resemble the Odysseus bracelet, and SJX says it is based on the Odysseus bracelet rather than a Wellendorff design. Gear Patrol says it is styled after the Wellendorff pieces. SJX and Gear Patrol both mention push-button link removal, and SJX notes that reassembling the sections can be fiddly.

Lange does not give a bracelet weight in the coverage we read, so we do not state one. We also found no stated clasp dimensions or link width, and no confirmation of whether the bracelet will be offered separately or on other Datograph Perpetual references. Anyone considering the watch should ask a Lange boutique for those details, since they affect fit and wearability on a case this size.

Movement and calendar functions

Calibre L952.1 is hand wound, with 556 parts, 45 jewels and a balance beating at 18,000 vph. Time and Watches gives its size as 32mm by 8mm. It is a flyback chronograph controlled by a column wheel, with a minute counter that jumps instead of creeping, and a perpetual calendar that shows date, day, month and leap year, plus moon phase and a day/night display.

The date is the outsize double aperture at 12 o’clock. Time and Watches says the calendar needs a one-day correction on March 1, 2100, and that the moon phase drifts one day from the real lunar cycle after 122.6 years. A rapid-correction pusher at 10 o’clock moves the calendar and moon phase together, and recessed correctors adjust each display individually.

The movement is visible through a sapphire case back. Time and Watches adds that the plates and bridges are untreated German silver, the balance cock is hand engraved and the movement is assembled twice. Some coverage, including the brief we were given, mentions L952.2. Every source we could read says L952.1, so we use that.

Price, edition size and availability

Production is limited to 50 watches. Every outlet we read gives that figure and says each case carries an engraved edition number. SJX says the watch is sold through Lange boutiques, and Gear Patrol’s author expects all 50 to be allocated already. That is an expectation, not a confirmed sell-out.

Lange lists the price as available on request. Some outlets offer guesses, such as Luxe Digital’s EUR 250,000 to 280,000 estimate and Gear Patrol’s expectation of a price in the hundreds of thousands of dollars. They are not official, so we publish no USD conversion and do not treat them as a price. SJX calls the pricing reasonable for the category, without a figure. Lange has not said when deliveries begin, and we did not find an official statement on how the 50 pieces are being allocated between boutiques or markets, so we make no claim on either point.

For market context, our report on watch price increases covers list-price moves this year, and the October auction preview covers secondary-market results.

Where it sits among grand complications

A perpetual calendar chronograph is among the hardest wristwatch combinations to build and finish. Lange’s version stands out for its flyback and outsize date. For comparison, Patek Philippe’s grand complication output is covered in our Milan Grand Exhibition report, and Vacheron Constantin’s approach to a thinner perpetual is in our Overseas Perpetual Calendar article.

We do not rank these watches here, since their designs, finishing and prices differ, and Lange has published no price for this one. What the platinum bracelet does is move the Datograph Perpetual toward the bracelet look that collectors have sought on neo-vintage Lange pieces, as Gear Patrol puts it. Whether that affects demand is interpretation; we have no sales data. The 2006 original was offered in platinum, and the new edition returns to that metal, which is the one clear link back to the first generation. Beyond that, the diamond markers and the bracelet are the elements that make this edition distinct, and both are decorative additions to an unchanged movement and case.

Background

Lange’s Datograph first appeared in 1999 with calibre L951.1, according to SJX and Monochrome. One brief we received said 2000, but the sources we read say 1999. The Datograph Perpetual followed in 2006 as the first Lange wristwatch to combine a chronograph, a perpetual calendar and an outsize date, according to Time and Watches. Our Datograph history covers the model, Lange grand complications the wider range, and the A. Lange & Söhne history the brand from 1845 onward.

Lange’s own site returned an error and Fratello’s article could not be read in full, so specifications are as reported by the outlets above and the water resistance is disputed. Prices are indicative; none has been published by Lange.
