If you fancy yourself as a bit of mathematician, know your way around numbers and are always up for a challenge then this watch might just be the one for you.
A great way to get your brain working, all the numbers have been replaced with some tricky looking formulas leaving you to do some serious maths before you realise you’re late for tea. With plenty of decimals, square roots, divisions and fractions, there’s enough work on this blackboard designed watch to keep any amateur Einstein counting with fingers and toes. So now you can unleash your inner nerd or you could just pretend that you understand all the equations when really you just memorized where the numbers are. (cheeky!)
