Navitimer 50th Anniversary movt?

[Importr]

Hello
Can anyone suggest a movt thats similar to the cal.41 that will fit the last 50th Ann. dial please?

Try manual wind Seagull (close subdial spacing). If not, Valjoux 7750.

Hi
Not too sure about the 7750/7753, as u said cos of the spacing. The manual wind Seagull doesn't have a calendar does it?

No calendar. Then try Rolex modded second subdial at 6. May be problematic though (again no date).

The real deal is using Zenith base movement if I am not wrong (very hard to source and expensive).
