Citizen Attesa eco drive case opening bits

Does anyone know where I can find the case opening bits for a three bit case opener For the above watch?
The holes are a crescent shape rather than the common square ones.
I couldn’t see any on Cousins website. Tried others no luck.
The watch has stopped and suspect the battery has died.
I don’t want to send it just yet to Citizen Uk. I like the challenge of fixing it myself if possible.
I’ll try and upload an image of the case back so you understand what I mean.
Grateful for any info. Attachment 17756

Square bits can be reshaped. Not sure if they are hardened, but a diamond file would work in any case

I would suggest putting some masking tape over the indents then trying and jaxa... I’d be surprised if it didn’t work regardless of the bit shape.

I have 5 pin Citizen case openers here all non marking.

I need the following pin measurement.
