We now have two options in the 1966 Chronograph line: the original 40 x 12.05 mm (Ref. 49539) in RG and WG (available with white or blue dial) which I have previously written in detail about [click here] and the 42 x 12.53 mm (Ref. 49542) introduced in April 2012 with the addition of a date display at 6 o’clock and some design changes to the dial.






The 40mm version houses the Cal. GP030C0: 10.5 ligne, 4Hz, automatic column-wheel chronograph movement with 38 jewels and a PR of 36 hours.



The 42mm version houses the Cal. GP3300-0057: 11.5 ligne, 4Hz, automatic chronograph movement with 57 jewels and a PR of 46 hours.






Personally I prefer the 40mm 1966 Chronograph on my wrist, but for some the larger size may be more appropriate. The addition of the date, while still retaining dial symmetry, may also be a useful complication for some owners.



The two subdials are a little less crowded around the centre of the watch in the 42mm version which I know some will also prefer.

And of course we have the addition of Arabic numerals on the 42mm 1966 Chrono. I prefer the less ‘busy’ original 40mm watch.




But you do get the same wonderful blued chronograph and seconds hands on either version.




The “miles per hour” on the tachometer scale may alienate markets using metric measures, but it is also a nice ‘nod’ to the chronograph designs of the 1940’s.







Do you have a preference?

About the Girard Perregaux Ref. 1966Chronograph

The Girard Perregaux 1966 Chronograph is a notable offering within the brand's classically styled 1966 collection, distinguished by its integrated chronograph function. This reference emphasizes traditional watchmaking aesthetics combined with a practical complication, positioning it as a more technically involved piece compared to time-only or simple date models within the same line. It represents Girard Perregaux's commitment to horological complications in a refined, understated package. The design adheres to the collection's established visual language, ensuring continuity while introducing enhanced functionality.

This particular iteration features a 40 mm case crafted from white gold, providing a substantial yet luxurious feel on the wrist. The watch is powered by an automatic mechanical movement, the GP03300-0064 caliber, which is visible through a sapphire case back. This movement offers a power reserve of approximately 46 hours. A sapphire crystal protects the dial, ensuring clarity and scratch resistance. The case dimensions contribute to a balanced presence, aligning with contemporary preferences for moderately sized chronographs.

For collectors, the 1966 Chronograph appeals to those seeking a sophisticated chronograph from a respected manufacture, without overt sporting pretensions. Its white gold case and classic design make it suitable for formal wear, while the chronograph complication adds a layer of horological interest. The choice of a display case back allows appreciation of the movement's finishing. This reference stands as a solid example of Girard Perregaux's capabilities in producing complicated watches with a focus on traditional design principles.

40 mm for me.

Not that the 42 mm case is ugly, not at all, but the presence of a date on such a dial is a pure NO GO for me. Best, Nicolas

I will follow Vlad's choice. 40mm based on ...

Movement, lack of date (that makes the dial more balanced) and the fact that it's a dressy chronograph (you may want to wear with long sleeve). Cheers, Nilo

Why chose?

I would happily get both. I do think the 42 mm has its charme. I like the look of the sub-dials and the larger size for a Chronograph would not bother me. I also like the arabic numerals. Maybe a compromise would be to get the 40mm in WG blue dial and the 42mm in pink RG white dial :-)

Those Arabic numerals ...

... are actually rather delicious. It was particularly obvious to me when I uploaded the images for this thread. I would choose the 40mm based on the size for my wrist, but the 42mm is a beautiful watch. Andrew

It's commendable that GP offered ...

... the choice of both 40mm and 42mm models, at least in RG. So at the moment we have the choice. I hope you can get the GP of your dreams one day, Damjan. Thanks for your loyal support of the brand. GP will impress you with some new offerings in 2013, I can promise. Andrew
