Good morning everyone, I ask you to you who are surely deep connoisseur and connoisseurs of the brand, I have this wrist watch exchanged in 2022, I am a private, not merchant, I own many watches but of another brand, this is the only IWC I have, I don't received the documents but only the declaration of origin, as often happens between private individuals, I found only one information throughout the web, relating to an old insertion of many years ago, struck by the fact that inside the case on the bord side they are renamed by hand in Roman alphabet the numbers 12 followed by 3 * XII and III * and that they do not seem to comply with the alleged recent age of the clock, does anyone have more information on the matter? Also because I thought in the event of sending it to the factory to have a certificate of originality, I thank everyone in advance those who will lend themselves, thanks
