At the time it was the only perpetual calendar chronograph produced on the market which lasted for the next 3 decades. The 2499 reference can be divided into 4 series and was discontinued in 1985. The present 2499 is highly important for a number of reasons. Firstly, it is from the second series that is distinguished by the round pushers and tachymetre scales. Secondly, it is the overall state of preservation with terrific case and dial with hard enamel scales throughout. What further elevates this watch to make it even rarer and more sought after comparing to the other 9 pink gold examples known is the dial. Upon further inspection, the connoisseur would note that the dial is known as a ‘flat dial’ and one of only 2 known examples. This example first surfaced at auction in 2021 and has been remained in the same prominent collection ever since. The watch itself is highly charismatic not only due to the flat dial that is original and well preserved. The case is also very well preserved with strong proportions and crisp steps to the lugs with hallmarks identifiable on each side of the lugs. Accompanied by a fitted Gobbi presentation case, one would conclude that although the bracelet is not confirmed from the Extract of the Archives, it would have been supplied by the famed Italian retailer.
