How do I adjust my Atmos clock?

Are Atmos clocks valuable?

The value of an Atmos clock may lie in its condition more than in its serial number or age. The most common Atmos types in fairly good condition can fetch anywhere from $300 to upward of $1,000. This is for model numbers 519, 526, 528 and 540. These clocks have the standard brass and gold-plated cases.
