One of the iconic chronographs made by the firm, the reference 4072 was produced over a period of about 30 years but in small numbers. Fitted with three different calibers over the years, this pink gold version equipped with caliber 434 is one of the only 252 examples produced. Still visible on the case are the two crisp gold punchmarks and the rare pulsation dial has been kept in excellent condition showing nicely raised enamel to the signature and tracks. Please note that according to Vacheron Constantin, the dial was later changed to the current one.
