having had the suunto gambit 2 & 3 and then the m400 thriller, the V800 is far above all. Functions are top and come up against suunto by the comfort of the watch is incomparable. Indeed, with these watches that track all activities and sleep, so it should be worn all the time out against all the others, the V800 is really comfortable to wear. Its shape, its size, its weight is really perfect, hyper flexible bracelet is also super nice. Anyway I am very happy with my purchase.
