GPS sports watches range from $199 to more than $1,000, and headline battery numbers depend on settings. This checklist uses an independent review, credited below, and applies it to a real brand.
1. Check battery life by mode
The Live Science review of the Suunto Vertical 2 lists up to 20 days of battery life as a strength, but battery claims depend on the mode and features used. Look for figures for the GPS mode you will actually use.
2. Judge the navigation tools
The same review praises advanced navigation tools. If you hike or run trails, check for offline maps, route following and return-to-start.
3. Decide how smart you want it
The reviewer notes the watch has no contactless payments or music storage and no built-in microphone. If those matter, check each before buying.
4. Check weight and size
The review calls the watch relatively heavy. Compare case diameter and weight with your wrist and with a watch you already wear.
5. Read the return terms
Check the return window, whether returns are free, whether exchanges are allowed and whether gifts must be returned. Buy the exact version you want.
An example: checking a brand against the list
In our Suunto US review we applied these questions. The store offers free 30-day returns and independent reviews are positive, but it offers no exchanges and we could not find a shipping policy.
