An iconic and influential design – yet this Solari Cifra 6 flip clock is currently on offer on eBay for just 99 pence.
The clock was designed in 1965 by Gino Valle, one of a series of similar clocks, this being the largest in that series. In terms of features, it's good for going on your wall or on a table (stand included), with mains power keeping those silkscreen printed digits ticking over. There's also a cream and white plastic case, plus a clear acrylic front.
It's not a perfect example – there are a few signs of age and missing a couple of screws (which are easily replaced). But that shouldn't put you off too much – this is a sought-after design and at retail, they tend to sell for fairly high prices.
