Hi. Nice watch, I love those T17. BTW it's the first time that I see a case with this shape. Is it signed & numbered by Omega?
My guess is that this predates Norman Morris's tenure as Omega importer. Remember that the import mark belonged to the importer, not the manufacturer. That's why some manufacturers had more than one. This movement is from the mid-30's. Don't think Morris took over until around 1939. gatorcpa
