Yes, we're back in the 1980s with this Steen Christensen and Erling Andersen design, specifically dating back to 1984 and offering minimalism for your wall.
It's still la conversation starter too and despite its slightly retro look, a piece that will work in most modern environments too. How does it work? Simple – it has a rotary dial, with the hour fixed as a dot, while the hand looks after the minutes.
It is made of plastic and is powered by a single AA battery. Yours for £49 in various colours.
