DAYTONA help please

[TurboWatch]

What year and serial number did Rolex stop making the Zenith Daytonas?

My research so far indicated that Daytonas with K serials were the ones with the new in house movement, and that the K serial production date was in 2001. What is the possibility that the P (2000 production) serial Daytonas have the Rolex in-house movement? or the P's all came with zenith movement?

Thanks for all your helps

From Larry's great post it would seem P was the start of the 4130...

I was told that some early P's had the zenith and the late P with production date of 2000 had the inhouse 4130.

Thanks again
