This set of 2 stainless steel watch spring bars will fit Omega Seamaster Midsize straps marked 98000112. These bars are used to attach the strap to the watch case.
These were not made by Omega but are high quality compatible parts made to fit straps stamped 98000112.
The image shows you where to find the 98000112 code — clearly stamped on the underside of the strap near the lug end.
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!
