Incredibly accurate moonphase requires no adjustment until the year 3821.
The Atmos clock obtains the energy it needs to run from small temperature changes in the environment, and can run for years without human intervention.
Its power source is a hermetically sealed capsule containing a mixture of gas and liquid ethyl chloride, which expands into an expansion chamber as the temperature rises, compressing a spiral spring; with a fall in temperature the gas condenses and the spring slackens. This motion constantly winds the mainspring. A variation in temperature of only one degree in the range between 15 and 30 degrees Celsius is sufficient for two days' operation.
In order to run the clock on this small amount of energy, everything inside the Atmos has to work in as friction-free a manner as possible. For timekeeping it uses a torsion pendulum, which consumes less energy than an ordinary pendulum. The torsion pendulum executes only two torsional oscillations per minute, which is 1/60th the rate of the pendulum in a conventional clock.
The first clock powered by changes in atmospheric pressure and temperature was invented by Cornelis Drebbel in the early seventeenth century. Drebbel built as many as 18 of these, the two most notable being for King James I of Britain, and Rudolf II of Bohemia. The King James clock was known as the Eltham Perpetuum, and was famous throughout Europe. It is mentioned in two works of Ben Jonson.
Experimental clocks powered by atmospheric pressure and temperature changes were next made during the Enlightenment. An early example is Cox's timepiece, a clock developed in the 1760s by James Cox and John Joseph Merlin. The oldest predecessor still extant is the 1864 Beverly Clock.
The first Atmos clock was designed by Jean-Léon Reutter, an engineer in Neuchâtel, Switzerland, in 1928. This noncommercial prototype, which predated the Atmos name but is now known unofficially as Atmos 0, was driven by a mercury-in-glass expansion device. The mechanism operated on temperature changes alone.
On June 1, 1929, Compagnie Générale de Radio (CGR) in France began manufacturing the first commercial model, Atmos 1, which used a mercury and ammonia bellows power source. On July 27, 1935 Jaeger-LeCoultre took over production of Atmos 1 while it developed a second design which used the present ethyl chloride power source. This model, later named the Atmos 2, was announced January 15, 1936, but problems delayed full production until mid 1939.
Today the Atmos clock is a refined hermetically sealed luxury timepiece, that, like time itself, marches along without interruption and without human interaction. |
* If shown above, Bracelet OR Strap lengths are measured to include the watch case and represent the MAXIMUM possible strap length.
Gemnation provides FREE bracelet resizing before shipment. If you know the size of the wearer's wrist, please let us know in the 'Special Request' section at the time of checkout and we will size the watch appropriately. Removed links WILL BE SENT WITH THE WATCH. Sizing is not an exact science; bracelet links vary in size and removing too many links or too few links may make the fit too small or too big. We therefore cannot guarantee the length of the bracelet or that it will be equivalent to the specified length. As a result, many of our customers take their watches to a QUALIFIED watchmaker to do the sizing with their watch in hand; expect to pay in the region of $5 - $25 for this service.
Watch bracelets that Gemnation resizes are still returnable. Unfortunately if an outside party is utilized to resize the strap, we can no longer accept the watch for return or exchange. Unforeseen circumstances may prevent us from resizing the watch bracelet. If this is the case, we will notify you before shipping the watch. Sizing requests are usually completed within 24-48 hours. If overnight shipping is selected in addition to bracelet sizing, please allow for additional time, or contact us beforehand to provide us with sufficient time to accommodate your request.
Please print our WATCH BRACELET SIZER to assist you with finding the correct bracelet size.

About Jaeger-LeCoultre
Since 1833, when the inventive Charles Antoine LeCoultre established this venerable watchmaker, it has produced some of the most outstanding and innovative timepieces. It wasn't until 1931, however, that the Jaeger-LeCoultre brand rose to international fame. It was then that the Reverso - an ingenious reversible watch - was unveiled to the public.
