    Just found this JLC...

    In the lounge!! :shock:

    Apparently it was given to my Grandfather as part of a settlement package. When he died, my Dad inherited it. I had absolutely no idea anything like this was in the family. Anyway I think it's pretty cool so I thought I would share a few pics :D.













    It's in absolutely immaculate condition, though unfortunately I know nothing about these clocks. From the inscription I would guess it was made in '73. It would be great if someone was able to offer a bit of info about them (and also tell me how to get it working!! :twisted:). Cheers,

    Chris

    amazing atmos :) great piece of engineering for back in the day

    been looking at getting one of those .

    great family heirloom mate

    they work on something to do with air pressure/ temperature and some liquid inside that keeps the clock going and doesnt need wound ever once its all set up

    Hello pretty sure these are powered by changes in temperature not winding,if you google Atmos,various articles will come up including restoration and repair specialists.My local watchmaker actually used to specialise in building clocks,but dont know if he has any experience with these.

    I just googled Atmos clocks............ what a piece of engineering !

    Manufactured to be virtually frictionless, with a miniscule power consumption. The power consumed by a 15 watt bulb would run 60 million Atmos clocks simultaneously.

    Wow, that's amazing the perpetual machine. Don't really do mantelpiece clocks but used to love my grandparents chiming clocks. How do they make them almost frictionless.

    A very handsome clock and a great watch / clock maker!

    Re: Just found this JLC...

    Much much more than cool! Thats one amazing bit of engineering horology brilliance that many many WIS's would give away a valuable part of their anatomy for......a clock grail- bow down :wink:

    Re: Just found this JLC...

    Here is mine ... looks to be the same as yours.

    viewtopic.php?f=1&t=72934&st=0&sk=t&sd=a&hilit=atm os

    The locking lever under the dial between the 5 and 6 numerals in your photos is in the 'off' position so the motor will not work until it is pushed to the 'on' position. See close up photo of same in my pics in above thread. Pushing the lever over to the opposite side should activate the clock - but before doing so make sure the clock is level by turning the levelling screws either side of the 'bubble' under the dial until the levelling bubble is central. Never ever turn the hands backwards. Never turn the hour hand by itself. Only alter the hands by pushing the minute hand clockwise. Servicing the clock is a specialist job - if it does not start working when the lever is unlocked it may need a service. The locking lever should always be pushed to the 'off' position before moving the clock. The lever should only be locked when the balance wheel reaches the end of its swing.

    Cheers

    Truely and heirloom piece. JLC timepieces just have a special feel to them.

    Re: Just found this JLC...

    It works on atmospheric measure , my parents bought one 25 years ago and it works perfectly, abeauty to look at !

    If it doesnt work , you can send it to JLC for a restotoration ! (worth it will probably not need serviced for another 30 years at least)

    Lovely Atmos clock but as Dunk said, servicing it is a specialist job.
    Seriously, you need a guy who is fully experienced in servicing Atmos clocks, someone having a 'good idea' simply will not do! :bounce:

    Re: Just found this JLC...

    Yes, I must have one of those before I quit the hobby.

    Maybe next time you are in London, pop down the Kings Road to Gutlins and have a look at their serviced examples. But best to get one complete with its storage/carrying case.

    Cheers

    Re: Just found this JLC...

    Love those Atmos clocks. Bought one recently on ebay. I've had it about 6 months now, and finally gotten it so it's a spot on +/- 1 second a day. Never needs winding as it is powered by bellows that expand and contract with a change in the temperature. Supposedly a 2 degree change can power it for 48 hours. Needs to be serviced every twenty years. :) Frankly I think every WIS should own one, particularly since they can be found at reasonable prices on ebay. And BTW, the one pictured by the OP is in terrific shape.

    Did you manage to start up the Atmos motor? If so, is it working ok?
