Antique French Marble and Gilded Brass Small Mantle Clock, WORKING! 7 1/2” Tall

2 3/4” x 4 1/4” x 7 1/2” tall, weighs a little over 3 lbs.

You can see damage to the enamel face above the 6. Otherwise, needs a good cleaning. But, this beauty works! I found a key that barely fits it (NOT ORIGINAL TO THE CLOCK) and would it up and it ticks away! SEE VIDEO. Highest bidder will get the clock and the key. I believe the decoration on the clock face is hand painted. 

I suspect this clock dates from the early 1900’s but I am not an expert in this area. Perhaps somebody out there in eBayland can enlighten us as to the time period of this clock? Thanks!
