Kalenji watch looks like the new 910 garmin. The big difference from their last xt model is the swimming support.
Here I'll show the con's (from DC rainmaker review). After all, we are their competitor

- Doesn’t record/display heart rate while underwater
- Doesn’t really work as a normal day to day non-sports watch (battery only 20hrs)
- Openwater mode is good, but still not fully solving openwater distance to high degree of accuracy
- Only supports one person at a time on watch, can’t split between husband/wife
