What “ASO” Means

ASO identifies the automatic night-shutoff version. This feature automatically silences the cuckoo and strike during the preset nighttime period.

Match the Complete Movement Number

The letters and suffixes in a movement number are part of the exact manufacturer designation and can identify important construction or configuration differences. Do not order by the base series alone.

Before ordering, compare the replacement with the movement already in your clock and verify:

• The complete model number, including every letter, suffix, and number after a slash
• Pendulum length or gearing, where applicable
• Hand-shaft length and dial clearance
• Bellows, lift, music, animation, and case-fit requirements

If you are unsure, contact us before ordering with a clear photograph of the entire back plate and its stamped movement number.
