A little unusual one this I think. I've seen similar clocks with a more 60s face but not this particular one. Also the back of those clocks looks like a cream coloured round insert possibly Bakelite, where's this one has a more modern (but older) clock mechanism. This needs replacing I think, so suitable for someone happy to swap over the mechanism to get it working again.
As it is I don't think it works as I didn't see any dial movement knobs on the back. I've not tried it with a battery at the time of listing.

The Retro 50-60's MCM Smiths mantel clock is a vintage collectable piece that exudes charm and nostalgia. Hailing from the United Kingdom in the 1950s, this beautifully crafted clock features a stunning pink and gold design that perfectly encapsulates the aesthetic of the era. A true gem for collectors of vintage and retro items, this untested piece is sure to add a touch of flair to any space with its unique and timeless appeal.
