Oh... excellent!Battery is the very common CR2025. Citizen on for the case back gasket is 393-00216 but iirc it’s a common o ring size, not a funky gasket.
Citizen Australia stopped repairing mine maybe 10 years ago and my local SCUBA technician has been keeping going but he said he didn't have any more batteries - odd. Anyway, I have a bunch of CR2025 so all I need to do is find a suitable O ring.
