What size is this o-ring?

Don’t know, comes on a kit with the battery and some silicon gel

Does this battery kit work with the aqualung i450t wrist computer?

The 450T takes a CR2450 which is advertised in this kit. The real question is if the oring fits the i450t.

Does this work with the i200 ?

If you are asking if the i200 will Bluetooth sync to the i300, I do not believe they will.

does this come with the tool to open the battery compartment?

Yes mine did come with the tool o ring grease and the battery hope this helps.
