A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar 25th Anniversary Watch

A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar 25th Anniversary Watch Watch Releases

The Lange 1 was introduced in 1994. Overnight, it became the benchmark and standard-bearer for Saxon watchmaking. For its 25th anniversary, A. Lange & Söhne has released the Lange 1 Tourbillon Perpetual Calendar 25th Anniversary Watch. Lange is really pushing the boat out for the brand’s 25th anniversary. This is actually the second-anniversary piece released to mark this milestone, with the first coming in the form of the Lange 1 25th Anniversary Edition watch released earlier this year. The Lange 1 Tourbillon Perpetual Calendar is the next step, the most complicated model in the collection.

This Lange 1 has incorporated a perpetual calendar and moon-phase indicator (accurate for 122.6 years). At 9 o’clock, Lange has opted for a retrograde day-of-week indicator in place of the power reserve. The month indicator, in particular, fascinates me. There is a rotating peripheral ring that hugs the dial. At 6 o’clock, just below the modest date window, a silver arrow points to the current month, and at the end of each month, the ring rotates to the next.

This dial layout is not new for the Lange 1. Ariel covered a previous version here, and one point he made that still rings true is: “Buyers of this watch not only need the ability to afford a $300,000-plus timepiece but also need to harbor the desire to want one that tries hard not to be showy and look like a $300,000-plus timepiece.” In other words, while this is a tourbillon, it is not visible from the dial side. Tourbillons have always been a sort of “flex,” if you will, in the watch world, and this particular setup is about as subtle as it can be.

A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar 25th Anniversary Watch Watch Releases


To most folks, the Lange 1 series will represent grail watches or things that will drive one’s ambition to achieve. This particular model does that and then some. With this Lange 1, we have a limited edition of 25 pieces, diamonds inlaid into the movement, and a list of complications that reads like a technical manual, all the while maintaining a class and legibility rare for pieces this complicated. In this special limited edition, Lange has included some very subtle details that just push it over the top for me, the biggest of which is the visible diamond endstone bearing on the tourbillon cage.



A. Lange & Söhne has made several iterations of the Lange 1 that I personally love. The top of the tree for me is the A. Lange & Söhne Grand Lange 1 Moon Phase Lumen. This tribute to the 25th anniversary of the introduction of the Lange 1 now comes close to knocking that one of its perch, though. The A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar 25th Anniversary Watch will be offered in a limited edition of 25 pieces and priced at $335,800. For more information on this release, visit

    Love this wat h, but can I have mine without the tourbillon text on the dial. Actually I dont really need perpetual calendar on the dial either.

    Small distractions on an otherwise mega watch.

  • Lingua Franca

    This would be the third 25-anniversary piece. The second was the Moon Phase.

  • DanW94

    So you have wads of cash just laying around the house, you know, under the mattress, in the freezer, stuffed in old coffee cans in the garage and you say to yourself, I’m going to get a watch. Do you choose this Lange 1 or the Ferdinand Berthoud Chronometer previously reviewed. I love Lange but would actually go with the FB. In my opinion the tourbillon on the Berthoud blows the one on this Lange out of the water.

    • Independent_George

      If I had that kind of money and had to choose, I’d buy a perpetual calendar. So between this and the FB Chronometer, I’d buy the Lange because of the perpetual calendar function. But then if I had more-than-I-can-spend money, I’d buy both.

    • egznyc

      You make a good point. The FB might be kind of a hot mess, but it’s definitely more exciting than THIS ALS.

      You would need a lot of old coffee cans, mattresses, etc. to have your plan succeed ;-).

  • Lingua Franca

    “At 6 o’clock, just below the modest date window, a silver arrow points to the current month”

    I think that window might be a leap year indicator, unless this is a new Big Date / Modest Date complication 😉

    • egznyc

      The arrow points DOWN at the chapter-ring date disc. That window is above the arrow and yes, I think you’re right about its function.

  • SuperStrapper

    I’m far less concerned with the hidden tourbillon than I am by the automatic winding. The watch is still incredible, I just would really want it manually wound.

  • egznyc

    Maybe it’s just me but this dial looks a little too flat and lifeless – at least for ALS and at this mega-price. Now just drop the last zero, make it all-platinum, and maybe I’d give it another look ;-).

  • egznyc

    Too rich for my wrist – or safe! But yeah, not sure it’s a robust design, though a manual wind would’ve made more sense anyway, to see that movement.

    • Jest Geoking

      I agree, a manual would have opened up the view but you would have to keep this wound. Could yo imagine forgetting and having to reset this watch? I would probably have to send it back to Lange. Oh shoot by the time it get back to me it would be stopped drats

    • Leonarr

      How about a good ol’ microrotor?

      • egznyc

        I love microrotors ;-).

  • Simonh

    I find that I can look at the sky and see what size the moon is for free.

    • egznyc

      From your icon, you’re clearly into our moon. Maybe this isn’t the right venue but I highly recommend the “Apollo 11” documentary.

  • Leonarr

    If the date is at six, what is the huge “25” for in the picture? Week number? What did I miss here?

    • DanW94

      The date is located at 10. (the 25 in the picture) The aperture at 6 is the leap year indicator.

  • frisbfreek

    I would actually love to see this but as an annual calendar. The month ring is a very clean implementation, and hopefully dropping the leap year and tourbillon will also drop a digit in the price? One can dream.

  • Jon Heinz

    “Of course it has a tourbillon….and the tourbillon has a diamond! But no, you can’t even afford to look at it. It’s hidden and may only be enjoyed by those who can spend twice the cost of the average single family home on a watch. Boom.”

    Seriously though, of course it really *is* awesome…and, of course will only be enjoyed by a precious few, LOL. The rest of us can drool at the pics. Good on ya if you can!

  • Lingua Franca

    But truly OCD people will complain that the differences between the phases of the moon are seen as right-left changes in illumination, as reflected in the original design.
