A brand matters a lots quality wise performance wise and trust wise also there are several watche brands in market but one of my favorite is fastrack. I been using last 1 year and I must say a great product and I never seen that and kind of lake ir performance issue is been raff and tuff products. And I also seen that it look really classy when you wear it you can also use in casual ware also even sports ware also. I experience it and the cell quality is really good huh I have my two fastrack watches past 1 years but in both of then I never change the cells its working nice without and lake. Its my personal opinion guys and I hope you its helps you
Thank you.
