Girard-Perregaux Vintage

Hello everyone,

I recently acquired this vintage Girard-Perregaux and have been trying to research its authenticity. From what I can tell, the movement, case, and overall construction appear to be consistent with an authentic vintage GP, but one detail has me puzzled.

The dial does not have a "Swiss" or "Swiss Made" marking at the bottom. Most vintage Girard-Perregaux watches I've come across seem to have one, so I'm wondering if this is a known variation from a particular production period, or if it could suggest that the dial has been refinished or replaced.

Has anyone encountered an original Girard-Perregaux dial without a Swiss marking? If so, I'd be very interested to know the approximate production period or reference. I'd also appreciate any opinions on the overall authenticity of the watch based on your experience.

Thank you in advance for any insights or information you can share. I look forward to learning from the community.

1960s. I wouldn't worry about the lack of "SWISS". The dial appears to be original.

The dial looks fine to me.

I suspect that the explanation for the absence of the typical reference is the unusual 1/5 second indices between each second on the dial. Unless GP had been willing to design a white exterior ring to accommodate SWISS", it would have rendered the function of some of those indices unusable.

Ironically, they really aren't of practical value without a stop-second complication, so it was essentially just a cosmetic design choice. But it is a nice, and attractive variation, in my view, and in good condition as well.

Very nice watch, and it is the first 36.000 vph watch (HF) and therefore has the 1/5th seconds division ( 5Hz ). So it makes sense like @Tony C. said to shows that functionality and to get rid of the Swiss marking in the early models, as i do see Swiss on most gold examples ( regulation ? maybe ) and the 39 jewel ones.

"In 1965, the Research & Development department of Girard-Perregaux achieved a breakthrough that would redefine mechanical precision: the creation of the world’s first high-frequency movement. Its balance wheel, beating at 36,000 vibrations per hour (5 Hz), allowed the watch to measure time with a level of accuracy previously unattainable.

Presented at the Basel Fair in 1966, this pioneering movement earned Girard-Perregaux the prestigious Centenary Prize from the Neuchâtel Observatory - a distinction reserved for the most remarkable horological advancements. "

Another nice read about it, and this one does mention a hacking function so now you can clear this up for us, does your second hand stop when the crown is pulled out ?
