I purchased this watch 3years ago till now it worked well with top Battery performance. It price is adequate too. Quality of design is ordinary, but with belt quality it is not good. Belt as teared of as manyas 3 times i.e for every year u should purchase new watch belt which is annoying. The best thing is its battery other then this with waterproof it’s good. The alarm sound is good but buttons work when we use it hardly. Compared to other products it’s an ordinary product
