#20/#21 Hermle Clock Barrel with Mainspring

#20/#21 Hermle Clock Barrel with Mainspring – Made in Germany

This #20/#21 Hermle clock barrel with mainspring is a quality German-made replacement component designed for compatible Hermle mechanical clock movements. The #20 and #21 barrels are the same size and are used in the time and strike train positions of compatible movements.

Because the same size barrel is used for both the #20 and #21 applications, this assembly can be used in the appropriate time or strike train position. Always verify the movement series number stamped on the back plate of your Hermle movement before ordering.
