2. How do I find
out the Model or Serial Number of my Clock?
You can best determine
the Model or 'Caliber' of your clock by visiting
our Gallery Page
and comparing your clock to others listed there
and you can e-mail us with the serial number and/or
description of your clock.
My Atmos Clock is currently not working, is there
anything I can do to fix it myself?
If your Atmos clock was
working properly until recently moved, or if it
was accidentally 'jarred' you can follow the instructions
for restarting your clock on our Atmos
Clock Repair Page. Our repair charges
are also listed on that same page.
Atmos clocks are extremely
sensitive and delicate and must be repaired by an
authorized Atmos Clock Professional only. It is
not advisable to try and repair your clock on your
own as you can easily cause more problems with the
clock that could result in more repairs then necessary;
therefore leave the repair of your clock
to an expert.
4. My Atmos Clock is an
older model and I believe the BELLOWS may need to
be replaced, how do I check to see if the Bellows
is good and can I buy one replace it myself in necessary?
An Atmos Bellows can last
25 - 30 years, sometimes longer depending on the
environment of the clock; A properly functioning
Bellows Unit should measure no more then 22mm
from the inside bottom to the outside edge,
when the unit is at room temperature. If the measurement
is more then 22mm at room temperature, the Bellows
is not functioning properly.
There is information on
the Internet explaining how to remove an Atmos Bellows
Unit and how to check if the unit is functioning,
however we do NOT recommend you try this on your
own without experience. As we say - consult an Atmos
Clock expert when your clock needs service.
How often do Atmos Clocks need to be repaired and
do they require any annual maintenance afterwards?
The Manufacture recommends
that Atmos Clocks be cleaned and repaired every
20 years or so, or as needed; some clocks can run
much longer before needing service, depending on
their environment. Eventually, an Atmos clock will
need to be cleaned and repaired at some point. Once
an Atmos is properly repaired, no "annual maintenance'
is required afterwards.
I'm concerned about shipping my clock off to someone
I do not know; do you have any references?
We have been successfully
repairing and restoring Atmos Clocks for many years
and we are very experienced in all makes and models.
We enjoy an excellent reputation with our customers
and we'll be happy to supply you with a list of
references upon request.
If I send you my clock, how long will the repair
take and do you offer any type of Warranty?
The typical time required
for the repair of an Atmos Clock is (approximately)
8 to 10 weeks. This length of time is required due
to speed adjustments that must be performed, once
an Atmos has been repaired. It's not unusual for
the speed adjustment period to take an additional
5-6 weeks to get an Atmos speed corrected.
Our Warranty period
for our Atmos Repair Service is technically 2
years; however, if there is a problem with
your clock after this period, providing that your
clock would only need a minor adjustment, there
would be no additional charge.
Is it safe to ship my clock and what shipping method
do you recommend?
You can find detailed Packing
& Shipping information on our Packing
& Shipping page. If you follow
the packing information on that page, your clock
will arrive to us safely.
How long will my Atmos clock continue to work once
it has been repaired?
Since most Atmos Clocks
run up to 20 years (or longer) before needing service,
once your clock has been repaired and providing
the clock is given proper care, you can expect your
clock to run for many years before needing service
If I decide to have the Brass Parts (Case) Refinished
by you, how long will the new finish last (and/or)
can you refinish only the top or bottom part of
Once your Atmos Case has
been restored and refinished by us, a clear coat
of lacquer is applied to protect the finish; providing
the clock is not excessively handled or improperly
cleaned afterwards, the newly restored finish will
last for many years.
We can refinish only a
portion of the Case - such as the Bottom Bezel (frame)
or the Top Bezel; however please understand that
the refinished portion(s) often will not match the
unfinished portions, i.e. one portion of the clock
will look "new" and the rest of the clock
will look "old", which is why we recommend
refinishing the entire Case if necessary or if requested.
Do you buy or sell new or used Atmos Clocks?
We do occasionally purchase
"Vintage" Atmos Clocks - either for resell
or simply for parts, please contact us for more
Do you sell Atmos Clock Parts Separately?
We sell Atmos Parts in
conjunction with the repair only. Our Contract with
the Manufacture (Jaeger-LeCoultre), stipulates that
we cannot sell Atmos "parts" separately.
We can and do sell replacement
Atmos Glass Panels, Glass Doors and Plexi-glass
Panels for all Atmos models, see our Repair
Are Atmos Clocks still manufactured and if so where?
Since the late 1930's,
Atmos Clocks have always been manufactured in the
same factory, in the Jura Mountains in Switzerland,
by highly skilled, master clockmakers and watchmakers.
New models of Atmos clocks are manufactured each
Can you recommend any clock shops near my area that
repair Atmos Clocks?
Repairing an Atmos Clock
requires knowledge and training; many respected
clock/watchmakers choose not to repair Atmos Clocks;
rather, they prefer to send their Atmos Clock business
to those of us in the Atmos Clock Trade, who is
more experienced with these clocks.
Are you Authorized by the manufacture to repair
We are authorized by Jaeger-LeCoultre
to repair all models of Atmos Clocks and we are
permitted to purchase parts directly from them when
repairing Atmos Clocks. Only authorized Atmos Clock
Repair Centers are allowed to purchase Atmos Parts
from the manufacture.
How do Atmos Clocks work?
Atmos Clocks are unique,
in that they run by "Perpetual Motion";
which means the clock runs under it's own power
and/or the movement actually "winds itself";
its energy being drawn uniquely from variations
in temperature, powered by a devise called the "Bellows
The 'Bellows Unit' is an
"accordion like" devise that is located
inside the Brass "Drum" in the rear of
an Atmos Clock.
When the temperature rises,
a special GAS sealed in the 'Bellows'
inside this chamber which then compresses a "Spiral
Spring' housed in the center of the Bellows Unit.
Likewise, when the temperature
falls, this special Gas condenses
('shrinks') and the Spiral Spring slackens.
This tiny back-and-forth
motion is actually winding the clock when needed.
A Fluctuation of only one degree in temperature
(plus or minus) is all that's needed in order to
expand or contract the Gas in the Bellows.
There are of course
many other parts that help drive and regulate an
Atmos Clock, however the Bellows Unit plays a major
role in the function of the clock.
