Chinoiserie clock

I wonder if one of your experts would be kind enough to comment on the origins of my old chinoiserie clock (pictured above). My grandmother gave it to my mother for her 21st birthday. On the back it says that it was made in England, and it looks to me to have a 1940s or 1950s face design. I’ve never seen another one like it and wondered if it is collectable or of any value apart from sentimental. It needs repair as it has been overwound and the key is broken. HELEN PEARCE, PEACEHAVEN
