I have had my Swim 2 for 5 month and been swimming with it open water about 5 times each week during that time. For the past 4 to 6 weeks I have noticed something annoying. On a regular basis (say about once a week or so) my Swim 2 watch have rebooted as I was saving my just completed swim. This reboot does not delete the swim, but it does make the watch forget all the historic steeps and the HR history for that particular day along with body battery and stress levels. It does however seem to remember activities like a bike ride.
Has anyone else had that problem, and is there a fix. I believe that my firmware is up to date.
