The 1950's were an important decade for Girard Perregaux. In 1951, they introduced a watch with a revolutionary new winding system that would become famous for its engineering feats, the Gyromatic. Because of its ingenious design and function, the Gyromatic watch became well-known. Today's offering showcases this classic boys size Girard Perregaux Gyromatic. It measures 31mm in diameter and has a classic vintage look. It has self-winding Gyromatic mechanism with very effective power transmission system that requires smaller wrist movement to keep the watch fully powered, intended to insure that the watch spends more time running at peak power level for more accurate timekeeping. This simple design eliminates key vulnerabilities commonly found in other automatic movements such as couplets, ratchets, and other delicate parts. It is original down to the dial and hands and in excellent condition. We have serviced the watch and for the finishing touch installed a high quality Teju lizard strap.
