Some details and observations on the Girard-Perregaux 1966 Perpetual Calendar 49547 from the current collection:
As I had a chance to play with it some time ago and try it on my wrist, so let me share some observations.
As you know, I own the 1966 Annual Calendar with Equation of Time…
one of my most cherished watches and it is easy to see that the dial layout of the Perpetual Calendar has a close connection with the 1966 Annual Calendar
It comes with a similar asymmetrical layout, displaying the months at a rotating disc with a dial opening and the date in an extra small subdial.
The Equation of Time unfortunately has been dropped, possibly to save space on the dial as it now requires a leap year indicator.
The Leap Year indicator is typical GP and quite playful with the “loupe” style hand. Like that extra touch of being different!
Another difference is that the Perpetual Calendar has a quick date set button at 8 but can still go without extra setting pins.
From the back side no real surprises, you have the Caliber 03300-0096 also with free-sprung balance and Microvar balance wheel, but compared with the Annual Calendar, it seems to me that the “perpetualness” has added quite some thickness to the case. The Case is 41mm in diameter and 12.55mm high, while the annual calendar is 40 / 10.72mm.
Available right now only in pink gold with the white opaline dial.
And it works well on the wrist.
So the question is, which do I prefer? Having a perpetual calendar is of course a much more elegant complication than “just” and annual calendar but then on the other hand, the annual calendar has the Equation of Time. I think I still prefer my Annual Calendar 1966 but if I would be in the market for a pink gold Perpetual Calendar, the GP 1966 would be a worthy contender.
