Well...I asked similar question 2 weeks ago...Below is the link:
I suspect that every sincere collector; when they reach a certain level, would ask the same question.
BTW, I have heard 5078P; 5079J; 3939HP and the 5074J and 5016P over the past few years.
What I can conclude is that:
1. Individual RP has its own characteristic sound; even the same model! In a special occasion; I heard 2 3939HP. Though both were excellent; I dare say one (a newer production) was better than the old produced one in terms of clarity.
2. Pure RP sounds better than RP with complications.
3. To me; catherdral gongs do not impress me very much; though the 5079 is really cripsy; loud (I was in a big room at that moment) and almost no sound of "mechanical vibration".
4. Compared between 5078 and 5079; I would go for 5078 in which the size; the design and the metal is more suitable to me
5. Compared between 5078 and 3939; it is really difficult. For 5078; it is louder and pure; for 3939H; it is cripsy and clear. Anyway; either one you would go wrong.
Finally, 2 questions remain in my mind.
A. Is the white dial really better than black dial?? Personally, I found the black dial is much more stunning; though it is not enamal. However; an enamal dial will reduce the wearability of the watch, agree?
B. I wonder if the "cathedral gongs" are possible in a 37mm 3939H as Mr Jerome mentioned, since the 5078P is 38mm in size and I query it can accomodate the cathedral gongs. Futher, if cathedral gongs is really good enough; why Patek manufacturer not put in other later models such as 5207 or 5104; I suppose these wathces are big enough to accomadate the cathedral gongs?
Hope buddies can share their view on this topic.
Just MHO,
