I'm looking to see if anyone can provide me a little help in figuring out more information about this watch. It was my grandfather's watch that was passed down to me. Back in 2017 I had it serviced by Omega but they were unable to do the Extraction of Archives, the boutique said it might have been due to a loss of some records due to a fire a few years ago? The information they were able to provide me was the following Caliber: 1332 Case Reference Number: 196.0175 I can get more pictures tonight if that would be of any help. Thanks!
