I have a Fossil Hybrid "Smart" Watch that uses this battery. I got about 6 months out of the battery that came with it new. I bought five of these, so I should be good to go for at least another 2 1/2 years, assuming the watch and the batteries last that long, which, at least with the batteries, I'm confident they will. I've got another hybrid watch that uses a different battery, and as usual, when it's time to replace the batts in that one, Battery Junction will be my first (and most likely only) stop to find them.

They're just batteries, but anyway, I've got no Cons to report, it's all Pros.
