Pugg wall clock at Ikea
It's the kind of thing you would expect to find on the wall of a European office in the '50s or 1960s. Perhaps even in a home. But we're certainly talking that era in both the style and the style of those numbers.
As for construction, it is made of stainless steel, with a glass front, powered by a single AA battery. Best of all is the price. You can secure one of these for £15 - which means you can always consider doing the multi-clock thing for different cities (as pictured below). The design lends itself to that perfectly.
