Good day! I Need help, want to buy watches there is a number, somebody can tell what hours and where they are. The seller has no documents and a box. Ref A23322 № 2439330
Are you asking if there is a way to authenticate the serial number for the calibre 23 Navitimer?
The only way is to take it to an AD, who will in turn send it to the service centre. Authentication doesn't just rely on just looking at the external features, it involves checking the movement too. In this case (pardon the pun) the Cal.23 Navitimer has a closed case back, so it would be removed to reveal the (hopefully) matching serial number on the movement.
If you posted a link or photos of the actual watch, we here would tell you straight away if we
thought it was real. Although none of us would authenticate it.
