I've had a fossil watch for the past 5 years or so and love it. Its a hybrid model so it runs off of a watch batter that needs to be replaced ever 9-12 months so I dont ever need to worry about charging it.
It also looks like a standard watch so nobody ever suspects it has some smart functionality. Its very barebones in that aspect but I can see whos calling/texting me, set vibration alarms, and control my music.
