Stumbled upon this scratch-brush while surfing for a nice seiko 6309 cheap.
Seems to work really good for those that want to keep those polished midlinks polished
(edit) about keeping the midlinks polished, I meant it might be easier to not brush them by mistake and with better control then a scotchbrite sponge
Have a look.

Looks damn sweet if you ask me
