‘Bim-Bam’ striking Junghans Mantel clock. 8 day.
The clock was very clean when I received it except that some grease or oil had hardened around a couple of the time train pivots causing the clock to stop intermittently.
Confession
I recall feeling particularly lazy on the day I repaired this clock not wanting to do any more than the bare minimum to get the thing working. I dropped both the mainspring barrels out (easy on these newer designs) and pulled the plates apart just enough to clean the time train wheel pivots without disturbing the Strike side.
