Citizen Aqualand JP2004/JP2000 Battery Change C520 CR2016

Citizen Aqualand reissue JP2004 battery change. The C520 movement takes a CR2016 battery, you'll need at least a caseback removal tool and a small screwdriver.
I don't know the Citizen part number for the gasket, if you know, please comment.
Update: Possibly gasket is 393-00045? Haven't confirmed.

This watch needs an eco drive update with a backlit display and nothing more (no screw down push buttons, no additional hands on the dial). Citizen will not listen.

That would be an excellent update.
