BTN 2 stuck

Does anyone have a tip how to remove (and get back on! ;-)) those tiny c-clips?

I just tried it with one here and it wasn't too painful, but I'd still be wary. Just some notes:

• Used a pair of thin needle-nose pliers to turn the clip around until the opening was pointing towards the back of the case, then pressed on either side of it to push it down. It came off easily BUT it pinged about 0.5m away - I'd try doing it somewhere where you're more likely to find it if it bounces off the table!
  
• To put it back on, it helps if you can hold the button half-in, half-out, so the ring cut into the button for the C-clip is right near the edge of the watch case - it then helps to keep the clip nice and flat. I then just pushed on the back edge of it with the needle nose pliers again.
  
  

But yeah, I think the main issue is losing the C-clip when it pings off :)
