The Value Proposition: The Amazing, Incredible, And Semi-Affordable Atmos Clock From Jaeger-LeCoultre
As the current new person at HODINKEE, it gives me no little delight to present – I should say, once again introduce – an old reader top choice: The Value Proposition. It’s been on break for quite a while however you’ve asked us consistently to bring it back, and we listened.
In Value Proposition we present to you a gander at a portion of horology’s greatest and best value for-the-money – watches that, in a world where cost increments have for longer than a decade shut increasingly more out of getting a charge out of mechanical horology, truly over deliver in the worth department. All in all this implies things in the under $10,000 classification and yet, you may see us periodically cover something like, say, a $15,000 minute repeater that sounds as decent as a $300,000 chiming complication, which appears to be improbable, yet hello, on the off chance that it exists, you’ll read about it here first.
Today, we should discuss the Atmos clock, from Jaeger-LeCoultre. The Atmos isn’t anything more nor less than one of unquestionably the coolest horological contraptions you can put on your desk at any cost, and it’s always been a secret to me why more genuine mechanical horology fans don’t have one. The Atmos is a clock that has no outside power source, and never should be wound by hand, nor is it powered (as most pendulum timekeepers are) by a suspended weight. All things being equal, the Atmos clock gets its power from minute changes in atmospheric temperature (henceforth the name).
The Atmos Marquetrie Le Baiser Clock
Here’s how it works: inside each Atmos clock is a container loaded up with ethylene chloride gas. As temperature rises and falls, the gas extends or contracts, causing the case to grow or contract thus. The wall of the case is associated with a short chain, which moves to and fro as the case grows or therapists, and this responding movement is utilized to wind the mainspring.

The purpose behind utilizing ethylene chloride is that it begins to vanish at around 54 degrees Fahrenheit, which implies the sweet spot for greatest volume change because of temperature is correct smack in the center of the most probable indoor surrounding temperatures. (As it happens it is likewise an intoxicant – a gentle focal sensory system depressant , truth be told – however in the event that you are airing out your Atmos check in search of a, will we say, loosening up interlude you presumably don’t deserve one.) In that temp range, the Atmos changes over warm varieties into mechanical energy proficiently enough that left to its own devices, the clock will run essentially indefinitely. The primary Atmos clock was designed by one Jean-Léon Reutter, who began making them in 1928 (there were prior clocks made that pre-owned temp changes for power yet they utilized bimetallic strips – of brass/steel – that flex to and fro as temp changes; this is similar standard behind compensating balances and besides, mechanical thermostats).
The Atmos RED Clock designed by Sir Jonathan Ive and Marc Newson; we went hands on with it in 2013.
In order to preserve energy, the totally gigantic equilibrium just swings twice each moment; it’s suspended from an Elinvar wire (Elinvar is a nickel-steel compound that displays insignificant changes in versatility when temperature changes, and it’s essential here since, supposing that you utilized a steel wire, you’d consider pretty to be swings in precision as temperature changed). A slowly twisting wire used to create isochronal motions in a clock is known as a twist pendulum.
The Atmos changes over warm varieties into mechanical energy productively enough that left to its own devices, the clock will run essentially indefinitely (the mechanism’s proficient to such an extent that a one degree change in temp provides sufficient juice for 48 hours’ run time).
The Atmos Hybris Artistica Marquetrie
As you can see this is pretty extraordinarily cunning and in the event that you can be excited to the center by sharp mechanical designing (and we assume you do or you wouldn’t be here) you likely want one already.
That’s the suggestion, prepared for the value?
The Atmos Classique Clock
The uplifting news is that comparative with the measure of interest and magnificence you get, an Atmos clock is fantastically reasonable. Now, don’t misunderstand me – Jaeger-LeCoultre makes some unimaginably costly Atmos timekeepers that are likewise wonderful, unique works of craftsmanship. For example, you can, in the event that you’re slanted, get yourself a dazzling marquetry-cased Atmos clock, with a theme after the popular composition The Kiss, by Gustav Klimt, for $242,000 (this is in reality still accessible and on the off chance that you want one, call up Jaeger-LeCoultre and tell them Hodinkee sent you). You can get one designed by the universally renowned Marc Newson, for somewhat less – about $129,000.
But you can likewise – clutch your socks – get a dazzling moonphase Atmos check in your choice of one of three completions for $8,800, straight from the boutique: the Atmos Classique Moonphase. In the event that a moonphase is excessively darned melodious for (you difficult realist, you) you can get the Classique for even less: $7650. We wouldn’t mislead you. (Used, they’re even less however purchaser beware: these tickers should be moved and taken care of cautiously and there’s an incredible chance of getting a lemon in the event that you don’t have the foggiest idea what you are about.)
Atmos Classique Phases de Lune, stainless steel
Yes, young men and young ladies, for less than you could undoubtedly spend on quite a few thoughtlessly designed, carelessly executed, and listlessly promoted watches whose most proficient viewpoint is how quickly they separate a moron from his cash, you could rather get perhaps the most fascinating, shrewd, and completely wonderful bits of horological creativity at any point to come down the pike. You can’t wear it on your wrist? Please – there’s something else entirely to life than showing off. Simply get an embroidered wristband that says “My other watch is an Atmos.”
We said up top that an Atmos can run “essentially indefinitely” yet that is a touch of wonderful permit; truth be told, Jaeger LeCoultre reveals to us they recommend a long term administration span depending on environment (for the most part a more blazing and more muggy environment will necessitate a more limited stretch between administrations) which should be possible either by a qualified nearby clockmaker, or the production in Le Sentier. – Ed.
