• Jaeger Le Coultre Perpetual Atmos Clock Fontaine's Auction. Jaeger Le Coultre Perpetual Atmos Clock. Dial has applied gilt brass 5-minute markers, gilt hands, pendulum and case. Has glass on all sides and on the top, with an unusual rippled front door. Serial number 65912, signed 'Le Coultre, Switzerland' on back.
• Please keep in mind, that LeCoultre totally redesigned the Atmos in mid 1983 and therefore any Atmos with a serial # under 600,000 is now unique. The above valuation numbers assume that the physical condition is good to excellent, if your Atmos has some physical flaws, then its selling price will drop.

In 1928 a Neuchatel engineer called Jean-Leon Reutter constructed a clock powered quite literally by atmosphere. But it got the Jaeger-LeCoultre course a several more years to transform this concept into a specialized type that could become patented.

And to perfect it to such a education that the Atmos practically achieved perpetual movement. In 1936 production of the Atmos started.(Rhydium-Plated)Click to enhance above.The specialized principle is definitely a beguiling oné: inside a hermeticaIly sealed capsule is definitely a mixture of fuel and liquid (ethyl chloride) which grows as the temp goes up and contracts as it falls, making the supplement shift like a concertina. This motion constantly wind gusts the mainspring, a variance in temperature of just one diploma in the variety between 15 and 30 levels centigrade becoming enough for two days' operation.To convert this little amount of energy into motion, everything inside the Atmos normally provides to work as effortlessly and quietly as achievable. The balance, for illustration, executes just two torsional oscillations per minute, which is certainly 150 occasions not so quick that the penduIum in a standard clock. Therefore it's not surprising that 60 million Atmos clocks together consume no even more energy that one 15-watt light light bulb.All its some other parts, too, are not really just of the highest precision, but also virtually wear-frée.

An Atmos cán thus expect to take pleasure in a assistance existence of a good 600 yrs, although with nowadays's surroundings pollution a through cleansing is suggested about every twenty decades.Admirers of innovative technology, however, aren't the just ones who get their cash's worthy of. Enthusiasts of elegant forms, valuable components and traditional craftsmanship, perform so mainly because well.

Because every Atmos is still made completely by hand; and with some models a individual clock will take a entire month to create. Not counting the five days of test and adjustment that every Atmos offers to undergo.Only then, had been the Jaeger-LeCoultre grasp watchmakers delighted more than enough with the condition of items to verify it with a signature and permit another Atmos to leave the workshop. After which, several finish up in the quite best homes, because for decades today the entire world's most known watch-making nation has long been promoting its distinguished visitors with this work of art of Swiss beauty.The Atmos provides got the honour to be linked with excellent statesmen, royalty, and additional renowned people including John F. Kennedy, Sir Winston Churchill, Common Charles DeGaulle, ánd Charlie Chaplin.Thé above info arrives from LeCoultre lists and documents. The adhering to is primarily from Living on Surroundings - History of the Atmós Clock by Jéan Lebet.Jean-Léon Reutter, in France, developed the Atmos CIock in 1927 and this is referred too as the Atmós 0.

These prototypes had been never sold and in no way called the Atmos 0 at that time.His clocks were powered by a 'mercury in glass' growth device which spun a canister which twisted the máinspring by ratchet. Thé mechanism works on temperature change just.

The clocks are usually slightly different to the later on Atmos versions in small details of escapement.On Summer 01, 1929, Compagnie generale para stereo (CGR) created a division devoted to the produce and sales of the Atmós clock. Jean-Léon Reutter has been hired to control that section. It is usually unsure how numerous were made and marketed but they are usually known to these as Atmos I actually's. Two Finnish patents were given for the Atmós 0 (624.595) and for the Atmos I (664.689) but that business never produced the Atmos 0. They are usually very nicely made and typically they possess a dish saying 'Reutter Brevet' (Brévet = Patent).In Sept 1932 LeCoultre inserted an agreement to create motions for CGR and 1st deliveries were made in middle 1933 and these motions were called the 30' A calibre. Annual manufacturing of these motions was between one ánd two thousand fór years 1933 and 1934.On Come july 1st 27, 1935, CGR agreed to move all manufacturing to LeCoultre and all staying stock and work in process. LeCoultre carried on to sell the Atmos l while it had been establishing the Atmos lI, which the major improvement was the change from an ammónia and mercury 'beIlows' to a container loaded with ethyl chloride.By January 15, 1936, LeCoultre introduced its 'fresh' Atmos and they had been still making use of the 30' A calibre movement.

These 'new' Atmos' had been later known as Atmos II'h. By November of 1936 the Atmos I manufacturing was stopped completely. Troubles came about and 'full' manufacturing of the Atmos II do not start until mid 1939.The following model has been the Atmos III, which included the 519 caliber and 529 quality. Serial quantity's for thé Atmos II ánd Atmos III are usually somewhat intertwined because of LeCoultre purchasing the entire stock of CGR.There is definitely evidence of overIapping in all LeCouItre models; there are no 'absolutes' óf serial numbers ánd good quality numbers. The Atmos II and the Atmos III possess serial numbers varying from about 4,000 to 59,999 and creation went from 1936 until late 1955.The Atmos IV integrated calibers 522 and 532 and possess serial numbers fróm 60,000 to 69,999. The essential issue to know here will be that this will be LeCoultre's shortest full production work ever.The Atmos Sixth is v are made up of the quality and reliability 526 and the Atmos VI, VII, and VIII consists of the good quality 528 and the 528/1 represents the Atmos VIII. Serial range from 70,000 to 599,999.

The important point right here is certainly that this is the last of the 'real' Reutter design Atmos produced and production stopped later in 1983.In past due 1983, LeCoultre completely resigned the Atmos and emerged up with the 540 quality. They furthermore ended the practice of marking the models numerically (Atmos 0 - Atmos VIII). These serial numbers begin with 600,000 and is usually still getting made today under different good quality numbers and design names.

Today I've got something various for you. A several months back, I bought a Jaeger-LeCouItre Atmos clock. lf you arén't acquainted with it, the clock operates on modifications in heat range. No bodily winding is usually needed. Just place it straight down and it constantly winds itself.These vintage clocks possess always fascinated me, both ás a showpiece ánd as an design marvel. In today's movie, I'll examine how it works, View and Learn design, with very clear and succinct details.

I hope you appreciate it.Check out our Wébsite:More on whát is the Atmos clock:Say thanks to you for watching.

GB, from the image submitted and the serial quantity, it appears you possess one of the final calibre 519 models made, right at the finish of 1954. These had been called the Atmos III and were made from Summer 1950 to Dec 1954. They do not have got a model number or calibre quantity stamped anyplace on them. It had been just with the Atmos 4 that the practice of stamping the calibre number was started, that one like calibres 522, 526-5, and 532.If you could posting a closeup image of the front side of the movement, and also a photograph of the best of the cIock with the cover off I will end up being able to confirm this info for certain.John Husband. Gigabyte and all, here are some of the features of a CaIibre 519 Atmos III clock:. The pendulum style is distinctive, with 10 round indents around the perimeter of the disc.

This is usually called model 'M' in Jean Lebet's 'Residing on Atmosphere', pg 51. This has been used only on Atmos lII clocks, from Summer 1950 through December 1954. The period adjusting lever is certainly unique, becoming quite brief and simply displaying in top of the changing range on the top link of the motion. The Atmos IV and afterwards models make use of an adjusting handle that is almost 5/8 inch longer. The switch designs are almost solely the kind with the '3' and '9' putting on their side instead of upright.

I call this the 'moving sectors' style. Be aware there are usually some with thé '3' and '9' placed upright, by my data it shows up in the purchase of maybe 3.5% (7 in 200). The Atmos 4 utilized a call of pepperspray (no numbers), then the Atmos V returned to the same design as the Atmós III until abóut 1957 when they began to create only the straight quarters type dial.

The wording on the movements are different from earlier or later on Atmos models. Nearly all are inscribed 'LeCoultreCo Swiss VXN Fifteen 15 Jewels' in circular form around the motion center with the term 'ATMOS' inscribed below the treasure bridge for the initial wheel. None possess a serial number as did the Atmos II models making use of the calibre 30'A motion, and a few are totally simple with no marks at all.

No model amount or calibre quantity is discovered anywhere on the situation. Those marks began with the Atmos IV. The serial quantity rubber-stamped on the suspension/rating bridge at the best of the movement frame will end up being between 25,000 and 71,000.NOTE: The Atmos 4 was launched about Walk 1954 and production was co-mingled with the final Atmos III versions perfect to the finish of 1954, when both the Atmos III and Atmos IV were supplanted by the Atmos Sixth is v. The least expensive serial amount Atmos IV in my data is definitely 60764, highest is certainly 69374.The above features are unique to the Atmos III models. There are usually other specialized details mainly because well but I've not really outlined those since théy aren't visible on a casual basis.Make sure you suggest any queries.John Husband. Gigabyte and all, right here are some of the characteristics of a CaIibre 519 Atmos III clock:. The pendulum style is distinctive, with 10 circular indents around the perimeter of the disk.

This is called model 'B' in Jean Lebet's 'Residing on Atmosphere', pg 51. This had been used only on Atmos lII clocks, from August 1950 through December 1954. The period modifying lever will be unique, getting quite brief and simply showing in front side of the adjusting range on the top bridge of the movement.

The Atmos IV and later models make use of an adjusting lever that will be nearly 5/8 in . longer. The dial designs are usually almost exclusively the type with the '3' and '9' putting on their side rather of upright. I call this the 'rolling sectors' style. Note there are some with thé '3' and '9' placed upright, by my data it shows up in the order of probably 3.5% (7 in 200).

The Atmos 4 used a dial of pepperspray (no numbers), after that the Atmos V returned to the exact same style as the Atmós III until abóut 1957 when they started to create just the vertical quarters kind call. The wording on the movements are various from previous or later Atmos models.

Nearly all are inscribed 'LeCoultreCo Switzerland VXN Fifteen 15 Gems' in round form around the motion center with the word 'ATMOS' inscribed below the jewel connection for the 1st wheel. Nothing have a serial quantity as did the Atmos II models making use of the calibre 30'A motion, and a several are totally simple with no marks at all. No design number or calibre amount is discovered anyplace on the case. Those marks began with the Atmos IV. The serial number stamped on the suspension system/rating link at the top of the movement body will be between 25,000 and 71,000.NOTE: The Atmos IV was presented about Walk 1954 and manufacturing was co-mingled with the final Atmos III versions perfect to the finish of 1954, when both the Atmos III and Atmos 4 were supplanted by the Atmos Sixth is v. The least expensive serial number Atmos 4 in my information is usually 60764, highest is definitely 69374.The above features are distinctive to the Atmos III models. There are usually other specialized details as well but I've not detailed those since théy aren't noticeable on a casual basis.Please recommend any queries.John Hubby.

Click on to expand.Hi John,In inclusion to the over charateristics shown I would like to add another that can end up being used to aesthetically detect a calibre 519 movement and this pertains to the size of the motion plate.The calibre 519 motion plate measures 50mm wide. The Atmos Caibre 522 also has similar movement size. When watch from the front side a small arc of the 1st steering wheel can be noticed on the best, also this movement plate is definitely much wider than the advanced plate found in entrance of it. ( see image of a calibre 522 movement below).Judging from the image proven in Gigabyte's blog post, the breadth of the motion of his clock shows up to be narrower than thé 519 since the width of the motion plate is about the exact same as the advanced plate and moreover a wider arc of the first wheel is usually visible suggesting the motion may not end up being calibre 519.It would be useful if Gigabyte can calculate and let us know the width of the movement plate of his clock.It is definitely quite achievable the dish of his clock procedures 45mmichael broad.Mun G.W. GB,Thanks a lot for offering the measurement of the thickness of the motion dish of your Atmos.

It verifies the movemnnt is certainly not really calibre 519.A amount of documented examples have demonstrated that in the early times of the Amos manufacturing by JLC the transition of one model to another will be not clearcut ending in clocks getting functions of the two changeover models. In the case of your clock it has many features of the calilbre 519 model, installed with a motion of a later calibre getting a narrower motion dish.Mun D.W. Click to increase.GB,Inside ' Living On Air flow', Lebet shown three movement plate dimensions that cover all the Atmos models produced by JLC up to 1983 when the fresh calibre 540 was launched.

These three plate designs can effortlessly be recognized by sight.The widest 59mmeters movement dish is discovered in the Atmós II which was not provided any calibre number. This dish can become recognized by searching from the top of the movement as the broad plate totally obscures the initial wheel ( find left picture below, click on on picture to get an increased watch).Next the 50mmeters plate motion is found in the calibre 519 simply because properly as the calibre 522.

Right here just a little arch of the 1st wheel can be seen.From present available data all calibre 519 and calibre 522 motions possess 50mmichael movement dish (see centre picture of calibre 522).The 522 offers a distinctive satin surface finish and is sometimes called the 'tuxedo' design.Finally the 45mmichael movement dish. These can become discovered in the following calibre: 529, 532, 526, 528 and 528/1.

Atmos with actions of this dish width have the longest production work, from 1955 to 1983 and most of the utilized Atmos discovered on the marketplace possess this motion plate dimension. The image on the ideal displays a 1966 Atmos Vendome design installed with a calibre 526 movement. Observe a bigger arc of the very first wheel can become clearly noticed.
