Up for grabs is a rare Girard Perregaux Gyromatic Deep Sea Diver, circa 1960s. This watch was a later iteration of Girard Perregaux’s Deep Sea line. This example is housed in a large, cushion 40mm case, and features a gorgeous aqua-blue roulette-style dial. This Girard Perregaux Diver is in excellent condition. The case has never been polished, and still shows its original bevels and lines. The dial is perfect, with no visible flaws. The original lume is still present in both hands and dial, aging to a lovely yellow color. The bracelet is not the original, GP-signed bracelet.
