G'day,
in fact, yes.
There´s not a great variety of design elements to set it apart from others; it´s round, same size as many others, three hands only and just with a date.
One might say it´s not special, but to me it does have a recognizable "look" in that it´s not a strictly classic piece.
This may become more apparent when looking at a variety of competitive models, such as the PP ref. 5127 or VC Patrimony. These are more "classic" in appearance, in that all design elements to me seem to be much closer to historic examples. JLC´s Master Control is larger and more "modern" in appearance, which to me creates a more "bold" than understated look.
Now the Vintage1966 goes back to numerous requests from the GP retailers world-wide, which called for a classic, more "dressy" look. A simple three-hands watch is a "must have" for a manufacture and this was completely missing in GP´s portfolio until 2006, so i do see good reasons to come up with a model like this. It´s simply expected from the 2nd oldest watch brand in some way 
Subsequently, particularly the size reportedly was subject of lively discussions at GP. The portfolio of GP did show a slight overhang of sportive models with massive and rather large cases, as well as colourful dials, thus a "simple" piece wouldn´t enhance the overall lineup with a larger case. That´s the main reason as to why it is 38mm in diameter, aside the fact this remains to be the most preferred size among the more classic pieces.
So that´s the environment the Vintage1966 stems from; the design itself underwent a rather long process with many many proposals and detail discussions.
Once you´re targeting "uncomplicated" pieces and classic looks, the watch actually doesn´t bring many design elements to set it apart from others. And exactly this was the challenge; adding colours or lettering of course is an option, as is a massive casework with an unusual shape. Now that´s already covered by a variety of GP models and therefore the slightly minimalistic approach was intentionally.
The name reminds of an era of great achievements in terms of accuracy, when GP cultivated the fast-beat technology with seemingly simple timepieces in the 60´s.
It is not a "retro-model" or a re-edition of a historic timepiece like the Vintage45, because it should be a modern watch that reminds of well-known designs but doesn´t copy them.
So in short, it´s more GP´s interpretation of a "classic simple three-hands watch" than a re-issue or a decidedly modern look. I find it to be quite timeless and not "old" in appearance, while avoiding the "flashy-ness" many, particularly over-sized, watches seem to have lately.
It´s different from other GP models, particularly in that it is one of few models without a complication beyond the date (and that´s an which was much discussed at GP during the development). It´s substantial without being too heavy or "flashy" for daily wear and probably will fit any dress or occassion, so within GP´s model range it makes for a pretty versatile piece.
One may say, it´s in fact "just a nice watch"!
But that´s what it should be and in the end, that´s what the markets asked for.
Personally i find this to add to GP´s portfolio very well and the Vintage1966 to be a pretty piece particularly on the wrist; for added complications, a more sportive look or a more bold casework, GP certainly does have a variety of others.
And on a "classic look WWTC", this would be a relatively large model (much larger than 38mm, because the movement commands a larger case). The worldtimer is a complicated timepiece, even if making it "only" a worldtime watch. So it would be different by nature and probably not that a perfect fit for an elegant evening suit as the Vintage1966 is.
That of course doesn´t say the WWTC can´t look stunning without additional complications, for which the WWTC Tourbillon might be the living evidence 
Cheers,
Peter
