This is a set of two new high quality spring bars designed to fit the Omega De Ville Prestige leather watch strap stamped 98000215. These are not made by Omega but are high quality parts designed specifically to fit this strap securely.
There are photos of your spring bars from multiple angles to help you assess the details before ordering.
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!
