Dating Your Atmos Clock

Though there is no known published reference books that date or 'grade' Atmos Clocks based on age or condition, the Chart below may be helpful in determining the age of your Atmos Clock.

You can also refer to our Atmos Gallery Page for help in identifying the make and model of your clock.

With the exception of the original Antique "Atmos I" and "Atmos II", (Mercury Reutter models) the following Chart lists Atmos Clocks beginning with some of the earliest models (or calibers) and their respective serial numbers:

Caliber / Model Serial Number Approximate Year Manufactured
519 25,000-59,000 Late 1940's to 1950's
532 Unknown, identical to Model 522 Unknown, only a few manufactured
522 60,000-69,999 1950's
526-5 70,000-107,000 1950's
526-6, 528 107,001-599,999 1960-1980
540's 600,000 and up 1980 -1998

How much is your Atmos Clock Worth?

Determining the value of an Atmos Clock depends on the model, age and the over-all condition of the clock and the actual value can vary significantly depending on what the market will bare at that particular time.

As of this posting, the more common types of Atmos clocks have been trading at prices as low as $300 and as high as $1,200.These prices would be reflective of a typical Atmos clock - such as a model/caliber 519, 526, 528 and/or 540 and with the standard brass, gold plated case.
Atmos clocks with Oriental Motif Cases (white or black plexi-glass), the Gruen wood case models or any other models with rare and unique cases will obviously be worth more then the types described above, depending on their condition.

Most Atmos clocks are "graded" by using the following guidelines:

Fair Condition - The clock runs, but does not keep accurate time and/or the Case may be badly tarnished and/or possibly 'pitting' or cracks in the metal.

Good Condition - Clock runs properly, the case has no pitting or cracks, however the lacquer finish has faded and/or has hairline scratches or minor blemishes in the plating.

Excellent Condition - Clock runs perfectly, the finish is bright and clear with only a few minor hairline scratches that are noticeable only at close inspection.

MINT Condition - Clock runs perfectly; case is in perfect condition, no fading and no highline scratches-even at very close inspection; often original box, packing material and documentation included.

A good way of determining the approximate value of your particular clock is to regularly visit on-line Auction Sites; look for clocks at auctions similar to yours, comparing your clock to identical ones with the final "winning bid amounts".

Prices at auction sites are often reflective of the current market value of most any item.
