I had purchased my fastrack watch 2 years ago from local market after comparing online price and also check its serial number on its website so I have been using this watch for 2 yrs as my regular driver so I will divide my review between pros and cons.
Pros:
1.durable.
2.battery lasts long.
3.easy to use.
4.service support great.
Cons:
Only con I think of is that for some people it would be quite heavy so keep this thing in mind before purchasing.
For me for last 2yrs its my daily driver so I can recommend it to anyone.
