Makes sense
I have purchased large Packs of these before BUT by the time I need the third Battery from the Pack, they last a couple of Weeks and then I throw the rest in the Recycle box!!! This way of buying makes sense and the Watch runs for longer because the Quality is better.

Replacement battery
Purchased to replace the same battery installed in December 2023. Has worked since then so we'll see how long this one will last.

Incomplete / wrong package contents
It says 2 batteries in the title, product description and on the package, but I only received 1 battery, in a different looking package than on the picture.
