To be fair, there are no waterproof smartwatches. I'm assuming the watch is IP67 water resistant like all the other smartwatches.
I think the watch looks decent. No better or worse than the other offerings on the market right now, 'cept maybe the LG Watch R. I just don't see a use case for me. For others maybe, but definitely not me.
What about the pebble? You can wear it swimming and in the shower.
