I've had a coupe of suunto watches, the last being the Ambit 3 peak which had a market leading gps. Suunto are committed to providing continuous software and functionality updates. I did my research before buying the Spartan and understood that it's far from the finished product, there's been about 5 software updates since I got it and each one greatly improves it. These updates include accuracy fixes, changes to the UI and functionality such as smart watch features and an alarm clock.. The updates are easy. The watch comes with a special lead with a USB at one end and a strong magnetic connector for the watch at the other. The USB is used for charging and, for updates, plugging into a computer. Plug the watch in, use the Movescount app and the watch syncs and installs any updates automatically. If you've had a suunto before, this will be familiar. The Spartan also syncs with a smart phone app and can automatically post up to other fitness apps like Strava. Lots of people worry that manufacturers will stop updating products in favour of their latest device. Suunto seem to buck this trend and are still producing updates for a number of their older watches. I'm not sure if the Spartan yet had as good GPS trading as the Ambit 3, but that may be down to the Spartan not having the GPS pod and opting for a hidden ariel inside. However, it is good and seems to improved from when I first got it a few months ago. This watch isn't yet as good as it can be, but the touch screen, excellent gps, smart watch functions and ongoing improvements make this a great watch.

I've given the Spartan for stars as I think future updates will make it a five.
