Currently, there are two interesting GPS watches on the market which I would find quite useful hiking, backpacking or mountaineering and worth to compare - the Suunto 9, Suunto Spartan Sport Wrist HR, Suunto Spartan Trainer Wrist HR and the Garmin Fenix 5X. Here are their features and differences.

All watches are currently the latest models from both manufacturers and their built in GPS feature, color display and battery life make them an attractive alternative compared to a smartphone with a GPS app - at least if you are frequently tracking your GPS or if you plan to go on remote backcountry trips.

In the past, I have always used my Suunto Traverse to log my GPS data (see picture below on a trip in Finnish Lapland).

However, there are certain features on the new watches which I found more appealing than on the Suunto Traverse - and in particular, I would prefer to have the Garmin Fenix 5X over the Suunto Spartan.

Why? Both watches offer similar features, with the Fenix 5X offering additional the possibility to upload 2GB of topo maps

Reasons for upgrading

When you own an old Suunto watch like the Traverse or a Garmin Fenix 3, then you are probably asking yourself if you should upgrade to the Spartan or Fenix watch.

The only reason why I would upgrade is the map feature of the new Garmin Fenix 5X. I think it is really cool to have a map on your wrist.

However, others might find the color screen or the touch screen of the Spartan more impressive.

Personally, I don’t care that much about the touch screen. However, the color display in combination with the map is a really cool feature.

Moreover, the Fenix 5X and the Suunto Spartan Trainer Wrist HR also has a heart rate monitor built into the back of the watch so you can measure your heart beat without wearing a heart strap around your chest.

However, it will still miss the map feature which I like on the Garmin Fenix 5X. On the other hand, the Suunto Spartan has a slightly better screen resolution.

The Suunto Spartan Trainer Wrist HR is probably the best solution if you only want to wear your watch occasionally or just to monitor your jogging in the city.

It is the least expensive and lightest watch of all models but also comes with less battery life which is acceptable if you do not do for example longer hiking trips.

Would this change my purchase decision? No. I still prefer a watch which is capable of uploading topo maps - the Garmin Fenix 5X.

The Suunto Spartan Trainer Wrist HR might be however a more appealing solution for those who need the lightest gear and don’t need the map feature of the Garmin Fenix 5X.
