I bought a casio edifice EDR539BK from a watch store in delhi. It costed around Rs 6000. The watch stopped working within a month. I had to replace the battery so soon.
This watch is not durable at all. The minute hand of the watch broke in just one fall. I took the watch to an authorised dealer for repair where he told me that the watch was fake. He also said that there are many other models of casio edifice sold online and in the market that are fake. I would not recommed casio edifice as there are high chances of getting a fake watch.
