Not sure on that Amer, the jubilee links are exactly the same as the bracelets for the PVD and gold-plate barrel Carreras, and one of the versions for the steel barrels. Stylistically it's a match for the steel/black Jarama and one reader has even seen it mounted on that watch. So I'm inclined to think it's not a put together; will have a look to see if I can find the bracelet codes for it, may shed some light.
