Better-known for grocery shopping, Sainsbury's has a home section too, with one or two interesting finds amongst it, including this Tu midcentury-style Dark Wood Flower Wall Clock.
There's a touch of the George Nelson about it, or at the very least, a 1950s or early '60s feel. If that's the look your after, this is great value. 35cm in diameter, it has that dark wood construction with contrasting hands, able to wall mount easily, as you probably guessed.
Powered by a single AA battery, you can grab one online for just £18.
