Rec. replacement for Garmin 910XT

[2xAGM114]

My Garmin 910XT is T.U. after four years. Runs are now in the 35 to 43,000 foot altitude. Last week the distance flat-out quit working. Not interested in another Garmin.

Interested to hear what other multi-sport watches people are training with. Needs to be waterproof, capable of doing tris (swim, bike, run in a single recorded event). HRM without a strap would be a plus.

Thanks!
