This set of 2 stainless steel watch spring bars will fit Omega Planet Ocean straps marked 98000397. 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 98000397.
Second image shows you where to find the 98000397 code on your watch strap – it is stamped on the underside, 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!
