Than a slide lever, which is found on the caliber 519 and all models since.Ī service from, E-mail address Murray Founder of ClocksmithsĪ specialist in Atmos and 400-day clock repair.Īlso, I overhaul most plug in electric clocks. You can tell theĭifference because the Atmos II has the speed adjustment as a turn screw rather Were not stamped on the bottom and are nearly identical. Particular caliber #, on the bottom of the case. The caliber's from the 522 to the Atmos' made today are stamped, with the Located on the bottom of the movement and you can see it through the front of the case.

The serial numbers are located on top of the movement next to the fast-slowĪdjustment. I have repaired that still have had the original bellow intact. This file contains is the serial #'s of over five hundred Atmos clocks that Use it anywhere on the Web including sales or auctions.

These serial numbers start with 600,000 and is still being Labeling the models numerically (Atmos 0 – Atmos VIII). In late 1983, LeCoultre totally resigned the Atmos and came Made and production stopped late in 1983. That this is the last of the “genuine” Reutter design Atmos Serial numbers start at 70,000Īnd went right up to 599,999. VII, and VIII consists of the caliber 528 and the 528/1 The Atmos V consist of the caliber 526 and the Atmos VI,

Here is that this is LeCoultre's shortest full production The Atmos IV included calibers 522 and 532 and have serial The Atmos II and the Atmos III have serial numbers rangingįrom around 4,000 to 59,999 and production went from 1936 So please don't get caught up in the “absolutes” of serial There is evidence of overlapping in all LeCoultre models, Of LeCoultre purchasing the entire stock of CGR. Serial numbers for theĪtmos II and Atmos III are somewhat intertwined because The next model was the Atmos III, which included theĥ19 calibers and 529 calibers. The Atmos II did not start until mid 1939. November of 1936 the Atmos I production was stoppedĬompletely. These “new” Atmos’ were later called Atmos II’s. The change from ammonia and mercury “bellows” to a canister,īy January 15, 1936, LeCoultre announced its “new” AtmosĪnd they were still using the 30” A calibre movement. LeCoultre continued to sell the Atmos I while it wasĭeveloping the Atmos II, which the primary improvement was LeCoultre and all remaining stock and work in process. On July 27, 1935, CGR agreed to transfer all production to Production of these movements was between one and two Movements for CGR and first deliveries were made in mid 1933Īnd these movements were called the 30” A calibre. In September 1932 LeCoultre entered an agreement to develop They are very nicely made and typically they have a plate (664.689) but that company never produced the Atmos 0. Granted for the Atmos 0 (624.595) and for the Atmos I It is unclear how many were made and sold but Jean-Leon Reutter was appointed to manage thatĭepartment. On June 01, 1929, Compagnie generale de radio (CGR) createdĪ department devoted to the manufacture and sales of theĪtmos clock. The clocks are slightly different to the later Atmos The mechanism operates on temperature change His clocks were driven by a “mercury in glass” expansionĭevice which rotated a cylinder which wound the mainspringīy ratchet. Were never sold and never called the Atmos 0 at that time. Jean-Leon Reutter, in France, designed the Atmos Clock in 1927Īnd this is referred too as the Atmos 0. “Living on Air – History of the Atmos Clock” by Jean Lebet.
