This set of 2 stainless steel watch spring bars will fit Omega Seamaster full size bracelets with clasps stamped 1503/825, 1514/825 and similar. These bars are used to attach the bracelet to the watch case.
If the back of your end link (the part that connects your strap to your watch) has the number 825 on it or the last three digits of the code on your clasp is 825, then these will fit your watch. These were not made by Omega but are high quality compatible parts.
If you are not sure if this will fit your watch or if you have any other questions, feel free to email me at Sales@TheWatchLink.co.uk. I'm happy to help!
