Carriage clock, Four-Glass Clock - Brass - 1920-1930

Travel/desk clock.
Brass case with beveled glass, adorned at the top and bottom with fluorite slabs (semi-precious stone with green/gray hues).
White enamel dial with Arabic numerals and garlands of flowers.
French manufacture as mentioned at the bottom of the dial and on the mechanism, dating from the 1920s/1930s.
The mechanism works but I think it needs cleaning and adjustment.
Anchor escapement.
Overall good condition, a few very small chips to the fluorite, barely visible!
