Oof...I was afraid of that. The last one I changed out was in Curacao (2021) and they had them in stock, sold me one, and loaned me their tools and a bench to switch it out quick. I can find them in Europe via the internet, but shipping to the US can be lengthy and sometimes costly. I'll keep looking....or have it switched out when I get to Grand Cayman in a few weeks. Thanks!
When I replaced mine, I did not pressure test it. I was just very careful removing the screws and cover. I greased the o-ring, and carefully replaced the cover and screws being especially careful to not over tighten the screws and strip the threads in the cover.
Just use a small screwdriver. It takes one with a small head anyway, but you need to use one that is short without a large handle (like a small precision driver) which you can't put a lot of torque into. Turn the screw in slowly until you get it good and snug, then turn it just a little bit more, no more than a ¼ turn. That should do it for you.Yeah, that's my problem. When i changed the battery of my Suunto Vyper Novo the first time it wasn't too tight and the second it was too tight and a screw broke
