Manufactured in the 1950s, this is a Maseitiso triple calendar moonphase chronograph in 18K yellow gold, powered by the renowned Valjoux 88, and housed in an oversized 37mm case.
It is equipped with the rare Valjoux Cal. 88, which adds a moonphase function to the legendary Valjoux Cal. 72C—famously used in the Rolex “Killy Watch.” The combination of triple calendar, three-register chronograph, and moonphase complication creates a highly mechanical and intricate design that is regarded as one of the pinnacles of vintage chronographs, celebrated for its overwhelming recognition and popularity.
The dial features applied bar indexes paired with alpha hands, reflecting a refined and high-quality construction. Together with the substantial presence of the solid 18K yellow gold 37mm oversized case, it exudes an exceptional sense of luxury and showcases a superb vintage character.
