Thanks for that, yeah I would have liked to have a little air puffer for dust, but I managed to do it clean. Just have to check very carefully before closing it up. I saw a kit on eBay when I got my tools which included all the things you suggest, I almost got it, but it didn't include the crystal press so I just went cheap and got the press and case back opener separately cheaper.The biggest challenge apart from knowing when to stop pressing the crystal, was getting the movement back in perfectly aligned with the chapter ring the first time, as the chapter ring moves easily, it can be tricky.
