Rolex DD4130 parts upgrade?

[wildrabbit]

Hi Fellow Watch Fiends!
I recently bought a Clean factory Daytona with a DD4130 that I will be using as a donor to my Franken project.
Does anyone have a recommendation of what parts to change out with Gen to make run better?
On the old site there was a post about recommended parts to swap our for 3135's, but has anyone done this for a 4130?

Thanks in advance!!

What have you found so far? I've got one coming as well that I might consider modding. The bridge, wheel and screws are the obvious ones if you want it to look more authentic.

Great list...thanks for sharing. I'm planning to undertake a similar project when my 4130 finally gives out. The original movement is still going strong after 2 years, even with no service after purchase!

Take a look at the balance wheel (432), there is a big difference between gen Parachrom hairspring and the rep one, the rep one can't adjust the wheel. Change this one is a good idea but it costs a fortune.
