Thanks for the replyTemple hey mate. I got some bigger spring bars fitted and initially it seemed great, but then after a day or so I could hear it rattling again. I couldn’t get a thicker bar in there so I think the SEL must have been machined massively narrower than it needed to be. In the end I did a bit of a bodge job and applied a thin piece of material between the watch case and the sel, silent now!
