A few weeks ago, my Fenix ββ5s drowned safely after being kicked by another swimmer on the same swim (always wear your watch under your wetsuit!). Now switched to Fenix ββ5 (which are bigger). In fact, on the hand turned out to be slightly larger and heavier. After about a week, about the same sensations. But the main disadvantages have been fixed - the screen is more comfortable, and the battery is much larger. In general, if the size is not so critical, then I would advise Fenix ββ5.
