I just picked this up from my OB, but decided not to wear it and pass it on to someone else. It'll fit all 19 and 20mm lug widths (the actual width is 19.5mm). I'm including the curved Spring Bars that were included which make it fit better on a 19mm lugged model. This is NOT the version supplied with the 60th Anniversary Limited Edition Trilogy models, but a newer version that was just released. The blue plastic wrap is still on the keepers, but I didn't get the plastic bag it came in (oops!) $150 OBO includes FREE SHIPPING IN THE USA. Thanks for looking!
