I need an AG1 battery, will this one work?

Yes, the 364 button battery is equivalent to the AG1.

does the 364 replace the sr621?

Yes, the 364 is a direct equivalent to an SR 621 and SR 621 SW.

This question is for the manufacturer. Can Duracell specify how long will it last once installed? I supposed they have tested it, so they should know.

That question is impossible to answer, even by the manufacturer. There are multiple factors that determine battery life. The most important is: What is the current drain of the device the battery is installed in?

Why does it say ‘ duracell – 319 1.5v silver oxide button battery’ but the battery i received was a 364?

That seems to be a typo by whoever wrote the ad copy.

Saved $25 the cost to replace at the jewelry store. So rSy to do, you just need to be carefull removing your watch back and to not break the glass. Not hard to do.
