Patek Philippe made the first ever wrist watch with the split-seconds complication in 1923. The watch featured a monopusher split-seconds chronograph and a white enamel dial encased in a 30mm yellow gold case. It was sold for USD $3M at an auction in 1999.

This piece inspired the gorgeous reference 5959, which was launched in 2005 and featured the incredible Patek Philippe hand-wound Calbire CHR 27-525 PS, which at the time, was the world’s thinnest monopusher split-seconds at only 5.25 mm in thickness.


The present reference is the Perpetual Calendar Split-Seconds Chronograph 5951p-012, this timepiece has a tonneau shaped case in platinum surrounding a beautiful white lacquered dial. black hands indicates the hours & minutes while two thin hands are for the chronograph function. It’s activated by the push-piece on the right side of the case.

The manual winding movement is visible through the sapphire case-back and has a power-reserve of 48-hours maximum.

The marvelous and rare timepiece comes on a black calf leather bracelet.
