This is a new high quality spare pin and tube set made to fit some Omega ladies De Ville Prestige watch bracelets. These are not made by Omega but are high quality parts designed specifically to fit watch links on a bracelet with clasps or end links stamped with the reference numbers below.
There are photos of your pin and tube set 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!
