Saturday night it's time to put the clocks forward, so here are five you'd be proud to tinker with...
Eye Clock £20
Based on a 1920s design, this clever tocker has cartoon eyes to indicate the time – left for hours, right for minutes.
Equation Clock/Graph Paper Clock £25
Like props from Big Bang Theory, these clocks feature complex sums to indicate each hour.
Hologram Station Wall Clock £60
Clever holographic numbers float in mid air above the face on this otherwise classic station-style clock.
Bang & Olufsen BeoTime £300
It's a clock shaped like an electric flute. How much more geeky do you want?
Oregon Scientific Crystal Weather Station £100
Not just a cool, contemporary clock but a cool, contemporary weather station with icons laser engraved in a crystal block.
