Hi everybody hope you are all well

I’m in the middle off changing the battery on my tissot touch II and in the manual it read battery is a cr1632 but now I have removed the battery it’s a cr 2032

So question is what’s wrong the book or the battery that’s in it , a quick Google search looks as if the cr1632 is a small battery but that could be just a generic pictures I’m looking at

Any help would be great many thanks Andy (iceblue)
