In first I thought that those products from Tata are valuable. But when I start using sonata watches it broke all my expectations about this brand.
Those watches are looks good but lose their shiny appearance after using even a month. In my chain watch accumulation of different stains on the surface lose the shine.
In the advertisement they assures the water resistance upto 50 atmosphere.
But my watch even under normal conditions gone wet and paused the needle movement.
Battery life of those watches are poor and for me it lasts only for few months.
