jcglobal 0 Posted January 1, 2011 I am looking to stock up on some batteries for Asian an Japanese Quartz Tag, Graham, and Omega, I have not opened them up, because I don't think I want to tackle that until necessary. Is there one variety of battery that predominates in these watches? Or is it basically all different sizes? Thanks. Share this post Link to post Share on other sites
greg_r 81 Posted January 1, 2011 Talk to trailboss99 on this one. He should be able to advise and may well also be able to supply via the RWGShop. Share this post Link to post Share on other sites
offshore 0 Posted January 1, 2011 Basically a few different sizes. SR920SW & SR927SW could be your main ones, although the most popular size across all movements (Chinese/Japanese/Swiss) is SR626SW followed by SR621SW. If any watches have digital displays they must use a variant with a suffix of W not SW. You will need to check each for its required model...there are over 70 different models of battery available for watches. O/S Share this post Link to post Share on other sites
