Hi guys, Firstly I would like to announce my self as a not so much experienced lover of Omega Watches, so I would like everyone who is experienced to let me know if my points below are true or not: 1. Before 2001 Omega supplied only the warranty card with the box. This card was not printed by Omega as far as the serial number and the model number is concerned. The AD wrote by hand all this info and stamped the card. This card was white colour. 2. After 2001 Omega started supplying also Chronometer, Pictogram, and other certification cards like Diamond, etc.... Those cards were red, and the number of the model and its serial number were printed by OMEGA, so the AD just stamped his business and the date of purchase. 3. Around 2007 Omega stopped supplying certification cards like Chronometer. They just supplied the warranty and the pictogram card. The latest included all the certifications printed with logos on the back of the pictogram card. 4. ..... Please write more info if you know.. Thank you for reading and helping!
