UW-GM - Urgos Grandmother .008mm Suspenison Spring
UW-GM - Urgos Grandmother .008mm Suspension Spring
Size: 5/16-inch width (a little more than ? inch), by 1-1/8 inch total length.
A small sized suspension spring for German-made, chain-wound, Urgos ("UW") mechanisms (movements) in modern (made after 1960) grandfather and grandmother clocks.
It is a unique spring design that only fits clocks with mechanisms by Urgos, made mostly during the 1980s, including clocks by Howard Miller; Ridgeway; Ethan Allen; Sligh; Trend; New England Clock Company (Co.); Seth Thomas; Wuersch; Mason & Sullivan; and others.
Fits popular Urgos 32-series mechanisms, including: UW 32001, UW 32002, etc. (In general, any Urgos UW mechanism that begins with "UW 32" and then 3 more numbers, will take this suspension spring). Example: UW 32166 (this is UW "32", and then "166"). Also, fits mechanisms numbered with a "UW 32" and then a "slash", such as: UW 32/9; UW 32/57; UW 32/61, etc.
