So, I have exams in a few weeks. If I pass "fingers-crossed", I would like to treat myself to a garmin watch. So my activities mainly is walking both outdoors and treadmill, and swimming open water in the sea (mainly in warm weather). I do not want to be able to have pay facilities, but the other features are nice such as music support. My price range would be under £200. Does anyone have any suggestions. TIA.
