Patek Philippe wouldn’t produce another split-seconds chronograph until the reference 5959 was introduced in 2005, fitted with an all-new, in-house ultra-thin movement, the calibre CHR 27-525 PS, and housed within a 33 mm platinum case. The caliber was an extraordinary achievement in fine watchmaking history as it was the thinnest split seconds chronograph ever created at the time. Executed as a single-button split seconds chronograph, its design brilliantly demonstrated the prowess and know-how of Patek Philippe in the field of complications.

Ref Variations: 5950, 5950A, 5950A-001,
