I bought this watch 1.5 years back.I have started using that.It worked properly.For the last few months I didn't wear it.Now the watch is not working.
So the problem is in the battery ?
On average, I've found that analog wristwatches that use a silver oxide (or alkaline) battery last about a year after a fresh battery has been installed. Digital watches, because they have no moving parts, will typically last longer on a set of batteries if you're not using the alarm or backlight function. Watches that use lithium batteries generally last two years or more between battery changes.
Based on your model watch, I would guess that your battery has run down too far to power the movement. A fresh battery will probably fix your watch. Hint: in the future, if you aren't going to wear your watch for a while, pull the stem out into the "set" position. That will stop the movement and extend the life of your battery. When you want to wear the watch, simply set the time (and date, if you have a date window) and push the stem back in.
