Ever­ything you need to know to ope­ra­te your Atmos clock

Inst­ruc­tions

On this inst­ruc­tion page you will find detail­ed infor­ma­ti­on on how to use your Atmos clock. We exp­lain how to pro­per­ly lock your clock, whe­re to best place it, and how to adjust it. 

COR­RECT LOCKING OF THE ATMOS CLOCK

If you want to lock the clock or adjust the time, you must wait until the pen­du­lum has tur­ned com­ple­te­ly to the right. Only now move the locking lever, which is loca­ted under the dial, from left to right and lock the pen­du­lum. Make sure that the move­ment is smooth and even.

COR­RECT LOCKING OF THE CALI­BER 540

When locking the cali­ber 540 (pro­du­ced from 1984 — 1987), the­re are some pecu­lia­ri­ties to con­si­der. As with other cali­bers, the locking lever, which is loca­ted here under the dial, must be pushed to the right as far as it will go. Again, make sure that the rota­ting pen­du­lum has tur­ned all the way to the right befo­re locking the lever. The main pro­blem here is that the last third can be qui­te dif­fi­cult to go. It is cru­cial, howe­ver, becau­se the lever locks into a cam that is not visi­ble on most models. This is the only way the pen­du­lum is secu­red and can­not come loo­se during trans­port. On the other hand, dama­ge such as a torn tor­si­on pen­du­lum spring often occurs. A bent or bro­ken regu­la­ting slee­ve, as well as a bent anchor fork or a dama­ged locking mecha­nism can also be possible.

Many of the­se cali­bers have the small attach­ment with a rub­ber plug on the locking lever, which is sup­po­sed to pre­vent it from slip­ping back when the tar­get is clo­sed. Unfor­tu­n­a­te­ly, this part likes to get lost over time. The ATMOS Ely­sée with polis­hed base, frame and colum­ns also has a locking screw in the base pla­te. If you tigh­ten this gent­ly with your fin­gers, ever­ything is secu­red and hard­ly anything can go wrong.

THE RIGHT LOCATION

Choo­se a quiet and sta­ble place for the Atmos clock. As few vibra­ti­ons as pos­si­ble should be trans­mit­ted, e.g. from the floor. Loca­ti­ons on out­side walls or the win­dows­ill without too much direct sun are pre­fera­ble, here the­re is a more con­stant tem­pe­ra­tu­re chan­ge. This hel­ps the clock to draw ener­gy. Direct sun loo­ks nice, the light refracts on the many struc­tures of the clock, but per­ma­nent­ly can fade the dial.

SET­TING UP THE ATMOS CLOCK CORRECTLY

If pre­sent, first loo­sen the locking screw loca­ted under the clock. It is important to uns­crew it as far as it will go.
Place the clock on its inten­ded place and align it as well as pos­si­ble with the help of a spi­rit level and the front feet. Many clocks have a built-in level for this pur­po­se. Now set the time as descri­bed in the next section.

SET­TING THE TIME

If not done, lock your clock. Wait until the pen­du­lum is tur­ned all the way to the right and then move the locking lever to the right side. If you are unsu­re, plea­se read the sec­tion Cor­rect­ly locking the Atmos clock.

When set­ting the time, the­re are a few basic points to keep in mind with your Atmos clock:

  • Never turn the minu­te hand backwards.
  • Do not touch the dial with your fin­gers. After years, the smal­lest par­ti­cles of sweat will cau­se stains on the dial that can­not be removed.

Once you have locked your clock, set the time a few minu­tes ahead of the cur­rent time, pre­fer­a­b­ly using a radio-con­trol­led clock. Now turn extre­me­ly care­ful­ly and set the time, only at the minu­te hand and exclu­si­ve­ly clock­wi­se. Wait until the set time is reached and slow­ly and even­ly release the locking lever. On some clocks, this is some­what slug­gish due to con­struc­tion and age, be sure to release the lever slow­ly and do not give the pen­du­lum any extra swing. Over­win­ding the pen­du­lum would cau­se dama­ge to the pal­let fork. The pen­du­lum should now turn free­ly and will take a few days to find its swing. The­re­fo­re, you should let the clock run for a few days befo­re fine-tuning it.

If you want to set your clock from sum­mer to win­ter time, i.e. one hour back, note to turn the minu­te hand for­ward 11 turns (hours) to reach the desi­red time.

FINE-TUNING THE TIME

Every Atmos clock can and should be read­jus­ted from time to time after it has been suc­cess­ful­ly com­mis­sio­ned and per­fect­ly ali­gned to achie­ve the desi­red accu­ra­cy. You can adjust an Atmos to ama­zing accu­ra­cy, with a litt­le love and pati­ence of cour­se. The­re are dif­fe­rent Atmos vari­ants, but all of them can be adjus­ted in the same way:

Abo­ve the dial, the­re is a small adjus­t­ment lever on each Atmos watch. The­re are also spe­cial vari­ants, like a tur­ning wheel on the old and rare “ATMOS II” models. But the princip­le is the same.

The adjus­t­ment is limi­ted to the left and right and mar­ked at the stop in each case. Eit­her with the minus and plus sym­bol, with “s f” (eng.: slow/fast), or with “r a” (french: retard/avance).

Moving the lever to the left (-/s/r) always means slowing down the time and moving the lever to the right (+/f/a) always means spee­ding up the Atmos clock.

The levers are adjus­ted smooth­ly and do not lock in any posi­ti­on. The indi­vi­du­al lines repre­sent appro­xi­mate­ly 10–15 seconds of advan­ce or retard during the day. This gives you the pos­si­bi­li­ty to cor­rect the advan­ce or retard by yourself for about 1 minu­te per day.

In the ATMOS II models, this is done in a more com­pli­ca­ted way by a rota­ry wheel, also cal­led a fine adjus­t­ment wheel. The­se are avail­ab­le in the vari­ant direc­ted to the rear (ear­lier ATMOS II) or to the front (ATMOS II around the 20000 num­ber). You can remem­ber: tur­ning to the right (clock­wi­se) means slower, tur­ning to the left (coun­ter­clock­wi­se) means fas­ter.  One full turn gives you about 15 seconds in speed per day. But here you should pro­ceed care­ful­ly and “approach” the desi­red result slowly.

WHAT TO DO IF THE ATMOS STOPS?

This is important becau­se expen­si­ve mista­kes are often made when try­ing to restart a good pie­ce. Mista­kes that ulti­mate­ly usual­ly break some­thing can cau­se dama­ge. Of cour­se, the clock can­not start run­ning again on its own. It needs your care­ful help for this!

WHAT NOT TO DO:

You should in no case sim­ply turn the minu­te hand and try to set the time. Do not touch the clock hands!

Some­ti­mes we have been told, “I moved the minu­te hand for­ward and the clock star­ted up again.” Short­ly the­re­af­ter, it stop­ped again. What hap­pen­ed? The small sil­ver cylin­der at the top of the pen­du­lum column, when the clock has stop­ped, is sort of enga­ged with the anchor fork, it points for­ward. It is the moment when you can see the clock hand jum­ping a litt­le bit, every 30s half a minu­te for­ward. By moving the hand in this sta­te, you all too often dama­ge some­thing in the gear train and/or bend the fra­gi­le anchor fork and the watch can no lon­ger run pro­per­ly. If at all.

WHAT SHOULD BE DONE?

If the clock has stop­ped, care­ful­ly turn the rota­ting pen­du­lum about 180 degrees to the right with your fin­ger. Then arrest the clock with the arres­ting lever. Now you can set the cor­rect time at the minu­te hand as descri­bed in the sec­tion Set­ting the time. Then you can release the locking lever again. The clock will now start again. If it stops again after some time, you can be sure that the watch needs a revi­si­on. Often it will run again for weeks, mon­ths, or years. Depen­ding on what the cau­se of the standstill was. If you are unsu­re or need help, feel free to con­ta­ct us. Even if your clock needs a revi­si­on we are avail­ab­le for you.

TIPS FOR THE COLD SEASON

If your Atmos is pla­ced in a rela­tively cool room during the cold sea­son (con­stant­ly below 16–17 degrees cel­si­us), tre­at your clock to some warm­th from time to time. To do this, lock your Atmos as descri­bed in the sec­tion Cor­rect­ly locking the Atmos clock. This will secu­re the clock and you can put it in a war­mer room for a day or two. This way you will ensu­re the win­ding func­tion and your clock will thank you! When loo­se­ning the locking pen­du­lum, always make sure that the rota­ting pen­du­lum does not start with momentum.

REVI­SI­ON

We often recei­ve emails from con­cer­ned cus­to­mers who­se Atmos clocks have stop­ped. They often fear that a major repair is due and that the pres­su­re cell or the oscil­la­ting spring is defec­ti­ve. You don’t have to worry about that for the time being becau­se in 99% of the cases only an over­haul is due and if the watch has not been mis­hand­led, no spa­re parts are needed.

A revi­si­on is due with each Atmos clock depen­ding upon envi­ron­men­tal influ­en­ces and its loca­ti­on approx. every 10–25 years. The move­ment is dis­as­sem­bled into its parts, which are then che­cked and care­ful­ly clea­ned. The move­ment is then reas­sem­bled, its rate and accu­ra­cy che­cked and fine-tun­ed over several weeks. If parts, such as the pres­su­re box or a cra­cked tor­si­on pen­du­lum spring, need to be repla­ced, we will of cour­se con­ta­ct you after an initi­al app­rai­sal. If desi­red, gold pla­ting, nickel pla­ting, rho­di­um pla­ting, or sil­ver pla­ting of the case is also possible.

Just con­ta­ct us and we can send you a pre­pa­red, soft pad­ded ship­ping box to make the trans­port safe for your Atmos. We will then be hap­py to refur­bish your Atmos. If you wish a best-insu­red trans­port of valu­ables, we can also offer or orga­ni­ze this trans­port of valu­ables, from door to door. Just con­ta­ct us, we will be hap­py to help you.
