You don’t fancy spending several hundred pounds on the Apple Watch? Here are some other smartwatches to consider:

Sony Smartwatch 3 (£189). The closest rival to the Apple Watch Sport. A square-screened device running Android Wear software, with GPS built in, three-day battery life, and a waterproof design. Lacks a heart rate monitor.

Motorola Moto 360 (£200). One of relatively few smartwatches with a round screen, this is the most attractive Android Wear device and has a heart rate monitor, but like the Apple Watch must be charged daily. Changeable straps.



Pebble Time (£119). More than 67,000 people have so far pre-ordered this smartwatch on Kickstarter, with its week-long battery life its main selling point.





More than 67,000 people have so far pre-ordered this smartwatch on Kickstarter, with its week-long battery life its main selling point. Samsung Gear S (£270). The Gear S can be used as a standalone mobile phone for texting, calling and web browsing, although it needs a separate mobile contract. The Guardian only gave it two out of five stars.

LG G Watch R (£200). Another round-screened Android Wear device, this is chunky but its battery lasts for two days, and it’s also waterproof.
