Not just one eBay pick here, we have several – as we've spotted a seller who specialises in vintage industrial factory wall clocks.
Some of them are pictured here, all of which seem one-offs, but tend to be from the 1950s and '60s, as well as from eastern Europe. The clocks also seem to have battery quartz mechanisms fitted, so just need batteries to go.
These would look amazing in the right space, particularly apartments based in industrial units (but not exclusively). Prices vary, but go from £49.
