I bought my SM300 at the end of 2011 after doing the research which resulted in my post.................. http://forum.tz-uk.com/showthread.ph...litary-watches Although I have the original 1039/516 bracelet I have never used it as I am not a fan of the older Omega bracelets - too flimsy and the end pieces never seem to fit tightly. I have always worn my SM300 on a black leather Omega strap but recently fancied a change. I already had an Omega bracelet which I like - a NOS Omega 1181/215 bracelet which has been sitting in my parts box for around 10 years. Problem was that the last link width is 23mm whilst the SM300 is 20mm. Google images of 1181/215 bracelets........... https://www.google.co.uk/search?q=om...FYnbGgod6QsKvA I then bought a pair of new 633 end links and removed of the wider links from the 1181/215 until the end links matched the width of the 633 end piece. The 663 end pieces are nice and tight and a perfect fit. This is the end result.......... I think this bracelet style suits the SM300 and it is very comfortable too. If you are tempted to have a go consider the following........................ One of the problems with removing the wider links is that the bracelet becomes much shorter. This was fine in my case as I have smallish wrists but could be a problem for a larger wrist. Note that my SM300 has the black rehaut recently discussed on another thread............. https://omegaforums.net/threads/omega-sm300-165-024-without-rehaut.40154/#post-469094
