nuvolablue 2,051 Posted January 3, 2018 Hi all. This came loose on my GMT II clasp this morning. I've worked out I can just buy a friction tube to replace but not sure of diameter size? Anyone know please? Or how to measure? Many thanks. Sent from my SM-G930F using Tapatalk Share this post Link to post Share on other sites

Might be useful information for someone else in future. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F282779193893 19mm x 1.0mm Sent from my SM-G930F using Tapatalk Share this post Link to post Share on other sites
