The clock was apparently produced in Germany by Telenorma in there 1940s or early ‘50s and has a look that’s incredibly contemporary despite being the best part of 70 years old. Possibly more. It’s all about the being so minimal.
The clock has a matt black case, a dial made of aluminium and a glass front. The hands might look plastic, but are actually metal. it is described as being in ‘good age-equivalent vintage condition’ with some inevitable signs of wear, but that probably adds to the character.
Just a battery needed to power it and £99 to buy it.
