Chronographe Waltham des années 1960, cadran panda, avec Valjoux 7736

| | mm

While Waltham is deeply rooted in American industrial history, their late-1960s Swiss-made chronographs are pure racing gold. This example features a striking, high-contrast "Panda" dial—crisp black sub-dials set against a stark white background—framed by an aggressive, tonneau-shaped sports case. Underneath the hood lies the manual-wind Valjoux 7736, a robust, cam-operated movement featuring a full 12-hour register. It is a muscular, utilitarian tool watch that perfectly encapsulates the shift from mid-century elegance to the bold, racetrack-ready design language of the early seventies.
