5.Reference 2458 Observatory Chronometer for J.B. Champion – $3,992,858
This is one of those watches with chronometric certificates.
Special certificates are handed out to the watches once COSC, the Swiss institution tests the watches individually to evaluate their timekeeping performance.
However, when it comes to Observatory provenance we’re talking about something bigger!
Back in the day, Precision Contests were organized to verify the finest and most accurate movements. Needless to say, Patek’s stunning collection has won over 700 titles over the course of several decades on these competitions.
Joe Ben Champion requested the timepiece and shortly he became one of the most important clients of Ptek Philippe.
The luscious high-end timepiece does not cease to amaze being the only 2458 in platinum that also comes with a platinum bracelet, leather strap and an additional diamond-set dial to top it off.
