The middle of the 20th century looks to be the inspiration of this Mercury Clock by Newgate.
Ideal for any wall (but probably best suited to the kitchen), this industrial-style clock (you can imagine something like it hanging on various factory and office walls in the past) has a glossy case in a choice of black or red, a clean dial and bold retro numbers. There's also the hands of course, along with a contrasting sweeping hand for the seconds.
Sized at 35 x 35 x 9cm and powered by a single AA battery battery, it sells for £50.
