Box regulator clock - Wood - 1910-1920

Beautiful antique regulator clock in Biedermeier style. Estimated age somewhere between 1880 and 1910.
It could possibly use a little touch-up.
The clock could eventually be cleaned, as shown in the photos. However, at this moment, both the clock and the chime are functioning without any problems, and the clock keeps its time accurately.
No serious defects or wear of the movement to be detected.
Although it's an 8-day watch, it lasts two weeks.
Old key
Cabinet adjustment screws are missing.
