For sale is a sapphire caseback and movement ring for a Speedmaster. This caseback fits 861 and 1861 movements. It originally came on a Speedmaster I purchased that I replaced with the original caseback. It is in great condition with minor wear and one scratch likely caused by removal tool. I am looking for 60$ paypalled and shipped to the CONUS. Please PM me or e-mail me at jared808 at aol dot com. Thanks!
