I buy sonata ocean 1 year and still it works fine no issue in performance.
It is very much durable, I am saying it because many time my hand hits the wall and still there is no break in watch glass.
I buy this watch from flipkart
It cost me worth of 2100 rupee.
It is really waterproof because I myself tested it many times in swimming pool.
We get fiber strip and plastic design.
It comes with both digital and analogue timing system.
