Well, I was looking at sportier watches, primarily divers and happened across a Navigator Perpetual. Of course it's not what I was actually looking for or even a particularly water friendly watch, but I do find it captivating. It's also interesting that when the original two models came out, I thought they were too big. Now, however, the size seems fine, especially when I am comparing it against the larger wearing BP Fifty Fathoms, or even the GO Sport Evo.
After doing numerous searches, there is little commentary on this model and few acknowledge owners. I guess it brings up the question of why so little interest. While price plays a factor, there are numerous other sporty watches in the same type of niche that seem to spark more curiosity. Given that, is it such an oddity of having a perpetual complication with a casual watch? Is it also too much of a contradiction of having a busy dial with a Pilot watch known for their simplicity? The IWC Big Pilot, however, is quite popular and it also strays for the simple norm. Overall, I think this may be one the least mentioned GOs. Any thoughts why?
In terms of the Navigator line, I really like this model in particular. The dial seems to easily absorb the perpetual features without breaking up the dial's symmetry. Unfortunately, I don't seem the same symmetry when I look at the other models. The short hour hand of the time-only model just doesn't look right to me, albeit it's probably the best value. Similarly, I don't like how the "4" is cutoff on the panodate version as well as the starkness of the white date background. While I find this model with all of its contradiction appealing, it makes wonder if I am better off not combining a Pilot genre watch with a perpetual. Have you considered the Navigator Pereptual at one point in time, but ultimately reconsiderd? Any thoughts on these models would be appreciated?

It's been a while since I have seen a RG version, but I was surprised at how sharp looking it was. I thought it would be an odd pairing, putting a precious metal case with a Pilot watch, but I think it works. I am considering a SS version which I think is not only a good value, but also more in keeping with the style. I am still the thinking about the combination of casual watch & perpetual complication as well as the case size. I find it wears well on my wrist, better than a Pam or Fifty Fathoms, but it's still a big watch and niche offering.
In terms of the BP, I was actually referring to the 5004 since it's more similar in price to the GO, but your comparison is probably more appropriate. While the BP 5004 offers a different complication than the GO perpetual, the focus was on the complexity of the dial and lack of simplicity. IMO, it is one of one of the most popular pilot watches even though it's moves quite far from the more traditional somber dial. In terms of the BP perpetual, I find the dial way too distracting, and moves too far away from the pilot watch genre. Other than GO and IWC, I cannot think of another pilot watch perpetual calendar. For me, I am drawn to the dial and the complication and less so the pilot watch style. Best regards.
I believe there are two editions (at least) of this watch. I've got the limited edition RG one with the black dial from circa 2001 or 2002 (?). I'm not too keen on the recently released revision which, IMO, seems crowded and unbalanced.
The one I've got, however, is a gem. Its tightly construction with perfect heft The perpetual functionality is easy to read, yet a quick glance at the dial provides an uncluttered view of the time and the big date. I think the SS version is not as focused as the RG in this respect.
Anyway, check out this excellent review of the SS version (but try to get alook at the RG if you can).
