Gentlemen, wrong place to post if you're looking for a watch. Forget Casio. Go for Seiko or Citizen. How much is your budget?
A good Seiko Chronograph can be easily had for around Rs. 10,000. Citizen's can be cheaper. Casio even more. I would recommend looking at Fossil as well. Its a cheap reliable brand (american).
In Seiko, you'll be able to find a lot of variety in the Seiko 5 watches. Those are automatic (no battery required) but are not very accurate compared to a quartz watch but an Automatic watch is a classier thing to have.
And whatever you do, don't buy a replica watch.
