It may not be as high-tech as an Apple Watch or a Fitbit Ionic, but the Push Watch has a couple of things going for it. Firstly, as a watch it works without any need for apps or swapping out watch faces. It's a simple LED watch face. Secondly, its battery won't let you down at a crucial moment. And if you need any extra reasons, the company behind the watches is Irish, the gadget won't break the bank and 10 per cent of the profits from Push Day & Night and Push Rainbow watches is donated to the Irish Cancer Society.
