Twenty years after it first paired a flyback chronograph with a perpetual calendar, A. Lange & Söhne has dressed its Datograph Perpetual in black, set its hours in diamonds and, most importantly for collectors, given it a full platinum bracelet. The new reference 410.136E, unveiled this week, is limited to 50 pieces and sold through Lange boutiques with the price on request.

What is the new Datograph Perpetual 410.136E?
It is the familiar 41mm platinum Datograph Perpetual, with its case left unchanged from the 2006 original, reworked in three ways. First, the dial: a black-rhodium finish over solid silver, with silver-toned sub-counters that give the watch a reverse-panda look that, as WatchesbySJX points out, earlier versions never offered. Second, the hour markers are hand-applied baguette diamonds. According to Forbes, they are graded F to G in color and VVS in clarity. Two stones sit side by side at 12 o’clock, while 4 and 8 o’clock are left bare to make room for the counters. Third, and most talked about, the watch arrives on a five-row platinum bracelet rather than a strap.
The dial layout is pure Datograph: the outsize date window under 12 o’clock, a sub-dial at 9 for running seconds, the weekday and a day/night indicator, a sub-dial at 3 for the month, leap year and the jumping chronograph minutes, and the moon phase at 6.
Why does the platinum bracelet matter?
For many Lange collectors, the bracelet is the story. In the brand’s early years, its platinum bracelets were made by the German jeweler Wellendorff, and Monochrome Watches lists several early Datograph references that came on them, including the 453.135 and 453.035. Those bracelets have become collectibles in their own right: Monochrome notes that the auction platform Loupe This sold a first-generation platinum bracelet on its own for $116,000.
The new bracelet is not a revival of that design. WatchesbySJX reports that, while it echoes the earlier look, it borrows its construction from the bracelet of Lange’s steel Odysseus, with push-button link removal and a double-folding clasp with push-button release. In our view, that is the smart choice: it keeps the jeweler-like character that made the old bracelets so desirable while giving a heavy platinum watch a modern, adjustable fit for daily wear.
What movement powers the Datograph Perpetual?
Inside is the manually wound calibre L952.1, built on the first-generation Datograph movement rather than the later Up/Down. Forbes puts the count at 556 components, 223 of them devoted to the calendar, with 45 jewels and four screwed gold chatons. The chronograph is a flyback with a column wheel and a jumping minute counter. The perpetual calendar needs no correction until March 1, 2100, and the moon phase drifts by one day only after 122.6 years of continuous running.
The one figure that has not moved with the times is the 36-hour power reserve. WatchesbySJX flags it as a practical point: a perpetual calendar that stops must be reset through recessed pushers, so this is a watch to wear often or keep on a winder.
How did the Datograph become a collector’s icon?
The Lange name dates to 1845, when Ferdinand Adolph Lange set up his workshop in Glashütte, in Saxony. After decades of silence in the 20th century, his great-grandson Walter Lange relaunched the brand with Günter Blümlein in 1990, and the first new collection, led by the Lange 1, appeared in 1994. The Datograph followed in 1999 with calibre L951.1, and it quickly became the benchmark for the modern hand-wound chronograph: an outsize date, a precisely jumping minute counter and a movement finished in German silver, with the hand-engraved balance cocks that are the house signature.
In 2006, Lange added a perpetual calendar to that base, producing the Datograph Perpetual. Monochrome reports that the first-generation Datograph was made from 1999 to 2012, mainly in platinum, before the Up/Down took over. The Datograph Perpetual, by contrast, has stayed in the catalogue through gold and platinum versions, among them the platinum reference 410.025 on Lange’s official site.
Twenty years on, Lange has not changed the case or the calibre. It has changed how the watch is worn.
How much does the Datograph Perpetual 410.136E cost?
Lange has not published a price; the watch is offered on request through its boutiques. Monochrome’s Brice Goulard expects it to sit “well above EUR 250,000”, which is his estimate, not an official figure. For context on how other houses are pricing anniversary perpetual calendars this year, see our look at the Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin and Patek Philippe’s Milan limited editions.
For the Collector
- Where to buy: WatchesbySJX reports allocation through Lange boutiques only. Ask your boutique early; with 50 pieces worldwide, we expect established clients to be offered first.
- Price: on request at the time of writing. Treat any figure you see as an estimate and confirm directly with A. Lange & Söhne.
- What drives value: the platinum bracelet, the first black-dial and diamond-index configuration of the model, and the small run. Past results for Lange bracelets are encouraging, but past prices don’t predict future value.
- What to watch for: keep the box, papers and every bracelet link. On the secondary market, a complete bracelet and full set matter, as our pre-owned watch checklist explains.
- Daily use: with a 36-hour reserve, plan for regular winding to avoid resetting the calendar.
In our view, this is the most complete Datograph Perpetual Lange has made: the same honest calibre, finally on a bracelet worthy of it. The diamonds will divide purists, but the black and silver dial reads beautifully, and the bracelet answers a request collectors have made for years.
