Sunday delight, a pair of Girard-Perregaux Automatic/Date Chronometer's
Some delight on a lazy Sunday: a pair of Girard-Perregaux Automatic/Date Chronometer's!
To the left, Richeville - to the right, Chronometer HF.
A lot of similarities here - the C-shaped case, silver dial, applied index, chronometer, automatic movement, date...
But there is one significant difference, Richeville Automatic Calibre 32-19 (21.600 vph) vs. Gyromatic HF. Calibre 32A (36.000 vph).
You might say these two marks the steps before and after GP went into High Frequency!
