Hello, I am new on this forum, I am living in Grimbergen - Belgium, sorry for my bad English. I recently bought three Omega, all of them are NOS ! The first one is The Omega Sensor, working, but a few ink at the bottom of the display, I hope it can be removed... The two others Are Omega De Ville, well working, in mint condition (also NOS) Can anybody tell me more about those two "Omega De Ville" from the 80's...? Thank you in advance.
