Review on Compact Watch Repair Screwdriver Set: Micro Precision Jewelry Screwdrivers Kit 0.8-1.6mm, Extra Blades, Mini Keychain Screwdriver - Ideal for Eyeglasses, Jewelry, and Electronics Repair by Larry Cothran

When you need a screwdriver set small enough for watch batteries, use the smallest screwdriver and they work great. You no longer have to go to the jeweler to change the batteries, of course you should know what you are doing. And bring this to me if you know how to change watch batteries. You need this screwdriver to remove those tiny screws, this is the one and I've tried others and they didn't work. You will not regret the purchase if you know how to change watch batteries. By the way, have a magnetic screwdriver handy to unscrew the small screws, because the screwdrivers are not magnetic. I just found out you can buy a screwdriver magnetizer that works great with these screwdrivers from the same seller.
