I really like the Polar m400 for the external HR monitor (H7) but also really want a watch/tracker that has a silent alarm mainly for the ability for it to wake me up in a light sleep cycle. Are there any other brands you recommend with same features as the m400 but with the silent alarm function?

A:
Depending on what features you are looking for, Garmin, Withings, Polar and Misfit all make waterproof fitness trackers. I think the new Fitbit Flex is also supposed to be waterproof but I don't know much about it.
For reference, I did a lot of research before settling on the Garmin Vivofit 2. I used this fitness tracker in the pool without any issues, but I didn't like that I had to manually sync it with the app to see my data so I didn't replace it when the band broke.
