Well, one small ball and how I got it out. It's not as bad as it sounds.....honest.
Once I got the bezel off, all that was left was the remains of a spring and no ball bearing for that wonderfull "click" when you rotate your bezel. Being pointed in the right direction from Jsud2002 and a link to one of Roys hacks as I like to call them, I proceeded to find a Bic pen and my clippers and followed Roys instructions which can be found here.
Roys ball seems bigger than mine, so once I get a mitt full of spring bars tomorrow, I will be able to tell, but you get the idea of the job in hand.
There seems to be a mixed view on using these balls as they are not stainless steel, but Tungsten and over time may wear away the bezel. I dont use my bezel as it should be used, so in my case I dont mind using the Tungsten. If you prefer your balls of steel, they are about £3 for ten of the 1mm little blighters. Enjoy the pics.
