One of the great classics of the Patek Philippe Grand Complications collection between 1995 and 2011, Reference 5004 embodied the traditional, manually wound chronograph at its highest level. Its Caliber CHR 27-70 Q is based on a “Nouvelle Lémania” movement, produced exclusively for Patek Philippe and completely reworked in the company’s workshops, to which Patek Philippe’s engineers and master watchmakers have added a sophisticated split-seconds mechanism and a very fine perpetual calendar. The movement comprises 407 parts, meticulously finished by hand according to the workshops’ time-honored methods. Over the years, this rare combination of complications was housed in a case of timeless, discreet elegance in white gold, yellow gold, platinum, and a limited series in steel.

This Only Watch 2013 special Reference 5004T is the first and only version ever produced in titanium.
