Basically it should depend upon your need, what kind of watch you would like to prefer. Set your mind and then go for it. Their are lot of choices like digital, analog, Chronograph. Have a look at Amazon, Flipcart, Fastrack, Cadencewatches .
I will suggest (Cadence Harlock $ 34.99) at (www.cadencewatch.com
) as your budget is low, but this will beter option for you, as this one comes under your budget as you mentioned.
