Dje's 2009 post highlights the Girard-Perregaux 1966 Annual Calendar and Equation of Time as the most appealing new watch from SIHH that year. This article delves into why this particular model, with its elegant design and advanced GP033MO caliber, captured the attention of collectors. It explores the watch's blend of classic aesthetics with technical sophistication, positioning it as a standout piece in the realm of accessible haute horlogerie.
Each SIHH
session brings its share of dream watches. The Richard Lange Pour Le Merite
from Lange or the Vintage 1945 Tourbillon with three gold bridges from
Girard-Perregaux are such watches. The bad aspect of such watches is that they
will remain a dream for most of us!
Fortunately the
show also offers watches of great interest for the wish list!
Some may be
tempted by the Vacheron Constantin American 1921, like I happen to be, or the
Jaeger-LeCoultre Diving Navy Seals Alarm. In that area of watches that are not
so affordable, but still not impossible to reach Girard-Perregaux launched a
watch that you've already seen here. I want to come back to that watch
with you.
The new
Girard-Perregaux 1966 Annual Calendar and Equation of Time is my favourite
revelation of this year!

This 40mm pink
gold watch uses the already known 1966 case. The case is quite thin and very
classy.
It is fitted by
the GP calibre GP033MO. This automatic winding mechanical calibre uses the
proprietary Microvar variable inertia balance, providing better stability of
rate and increased precision. This balance brings the watch to the technical
level of a Patek Philippe Calatrava for instance.
Still the best
is to come! 
This watch
incorporates the annual calendar developed by Girard-Perregaux. This ingenious
design is based on a yearly rotation of a month wheel. The rotation of the
wheel dictates the date wheel, taking into account the length of the months
(except for February of course, set for 29 days).
The other
ingenious outcome of this yearly rotation of the month wheel is the indication
of the equation of time. The equation of time lever uses the month wheel as a
cam indicating the time difference between the solar time and the mean time!
Of course we've
seen annual calendar or equation of time watches for years. The pleasing aspect
of this 1966 is that the combination of the two is smartly engineered and so
efficiently that the watch is offered at a very appealing price point.

We all dream of
extraordinary complicated watches but isn't it particularly pleasing to
finally see a romantic and rare complication coupled with the most practical annual
calendar?
This watch has
instantly appeared to me as the most appealing watch of the last SIHH because
it is a full success. The design is pure and beautiful, the dial is highly
readable, yet indicates all useful information, hours, minutes, seconds, day and
month. The equation of time is the cherry on the cake, the little touch that
transforms a tool into a magical and philosophical object of desire. The fact
that this superb watch comes from a known and highly appreciated maker as a
possible choice is the best surprise!
Girard-Perregaux
is a very creative company and I have no doubt that we will see other nice
surprises from them in the next years.
I won't
wait so far to put this new 1966 on my wish list! No doubt I won't be
alone.
Cheers

The Girard-Perregaux Vintage 1945 line, introduced in 1994, draws inspiration from historical models, specifically a 1945 Art Deco piece. This collection is characterized by its rectangular or tonneau-shaped cases and a design language that evokes mid-20th century aesthetics. The Vintage 1945 series quickly became a cornerstone of Girard-Perregaux's offerings in the 1990s, reinterpreting classic forms with contemporary watchmaking standards. It represents a significant period for the brand in re-establishing its heritage-inspired collections.
Early models in the Vintage 1945 series typically featured stainless steel cases, though gold variants were also produced. The case dimensions varied depending on the specific model, often presenting a balanced profile suitable for dress wear. These watches were frequently equipped with automatic movements, showcasing Girard-Perregaux's in-house capabilities or finely finished outsourced calibers. The crystal was commonly sapphire, ensuring durability and legibility, while water resistance was generally suitable for daily wear rather than aquatic activities.
For collectors, the Vintage 1945 series appeals to those interested in neo-vintage watches that successfully blend historical design with modern execution. The 1994 introduction year marks it as one of the earlier and more influential lines from Girard-Perregaux's resurgence in the 1990s. Its various iterations, including time-only, small seconds, and later complicated versions, offer a range of choices for enthusiasts seeking a distinctive rectangular watch with a clear lineage.
The equation of time is an interesting complication, but for it to be useful, you have to know the difference between your local time and actual civil time (equivalently, the time of the average true solar noon in your current location). I doubt that many people know that off hand except maybe people living in Greenwich, UK, and most of them probably don't even realise it! Speaking of the obscurity of the equation of time, I've only known one other person who knew that December 21 (northern hemi
first of all, thanks a lot for this very interesting post, my friend. I know that you fell in love with this watch, I saw these sparks in your eyes, which means a lot! For once that a Manufacture releases a quite affordable EOT, it had to be said, and I'm very happy to see that GP did it! Not only affordable, but beautiful, too. But to me, I have another competitor for the tiltel of the most appealing watch, this year... Another pure moment of Poesy...: The VC Patrimony Skeleton. This GP is no t
The must desirable (affordability considered) watch of the SIHH 09. Most EOT has very crowded dial that almost need a user manual but this is simple and highly practical like you said. I can't help but noticed some similarities with this 1945 Off-center especially on the sub-printed-dials-black-red-lettering. photo borrowed from web This 1945 is a complicated-dial-simple-watch but the 1966 EOT is a simple-dial-complicated-watch. Makes me think that "thinking out of the box" does not always have
Please help me understand. I thought that the solar time is to be obtained from adding or subtracting the EOT from the time shown on the watch? thanks
To compute when the true local noon occurs you need to know the equation of time to get the difference between true local noon and the average local noon. But, you also need to know the time of the average local noon, which depends on your longitude (how far east or west you are). If you live in Greenwich, UK, no problem, they are the same, by definition. For everyone else, you have to add or subtract from noon, 4 minutes for every degree West or East of Greenwich, UK (and then make up for time
does the EOT function need adjustment end of Feb as well? May be a dumb question but I know not much of EOTs.
