the Rolex.Tudor connection

[Rolexman13]

I recntly found out that Tudor is actually a brother company of Rolex but are the ties between them still there? I'm a believer..

Note the similarities of both brands' diving models, chronographs and recently that of the sky dweller and the aeronaut (see pictures).
*Disregard the fact that Rolex has far superior craftsmenship than Tudor.


Does anyone believe that Rolex uses Tudor to test new models or features:
- Will we see a Submariner with luminous bezel, or no date magnifier and luminecent marker at 3 o'clock?
- Or perhaps a Daytona with a date either at the iconic 3o'clock positions where most Rolex date complications are displayed, or at the 6?
