Suunto transmitter o ring sizes

[Ian@1904]

I have a couple of old transmitters that I am thinking or connecting back to my kit. I am not paying £50 for someone to use a screwdriver.
I know the battery size, not sure about the o rings. I think the sizes are 25 mm x 2mm and 9.25mm x 1.78 mm. Does anyone know for sure?
Is there anything to beware of, such as being careful with the screws, which I suspect are self-tapping?

They sell kits of eBay for them - o-rings and battery and sometimes even the grease. On your head be it if you use them though (I might have used the odd one or 6 over the years). You might want to see if you can get your transmitters "fixed" as they did a recall on them a while ago. Maybe it will be worth it?
