I would wear it on a daily basis, for sure, but I don't attempt to pass my reps off as gens. If I am asked, I say it is a rep. If I was trying to pull it off as a gen, I would only wear it on special occasions, as freddy said.
I have the seagull version vintage Daytona and really like it. The only thing that bugs me is the placement of the subdial at 6. Otherwise, I quite like the rep. I don't care that the subdial at 6 is faux. The seagull movement is a very, very nice movement- about as nice a movement as you can get in an out of the box rep IMHO.
I believe the seagull would be much more reliable than the 7750 version, even a serviced 7750. I have read many threads on this forum and others concerning the DW or Spin 7750 versions, and I get the sense that the 7750 version, although visually superior to the seagull version, is not exactly bullet-proof and requires time, patience, money and a good watchsmith. I have had bad luck with 7750 movements in some of my other reps, so I will admit to being biased against the 7750 in general. However, I would not let a 7750 keep me from buying a watch I really wanted, I would just lower my expectations in terms of reliability and the need for servicing and repairs. If you are talking about a DW or Spin 7750, you are on the right track. If you are looking at a 7750 version that is not from DW or Spin, I would not bother.
So, do you want accurate looks, or better reliability? I can see arguments for both, particularly if you are using it is a daily driver, but it also depends on if you are passing it off as a gen. I would be careful about trying to pass off the seagull version as a gen, especially to a knowledgeable Rolex person as the subdial placement at 6 is a pretty obvious tell. I would personally take the seagull version if I wanted to wear it on a daily basis. If I was only wearing from time to time, I would take a Spinmaster 7750. Having said that, there are some extremely knowledgeable vintage Daytona people on this forum such as freddy, lhooq, sqpl and others that can give you better advice than me, as I only own the seagull (I did have a 7750 vintage daytona that was not from DW or Spin and sold it after it failed on me twice, even after service).
Just my two cents.
Cheers
