The Patek Philippe reference 5004 has become one of the greatest neo-vintage collectibles. Featuring a split-seconds chronograph function that allows simultaneous timing, it was the first serially produced Patek Philippe perpetual calendar model to feature such complications. A feast of technical mastery, the intricacy of the split-seconds function added to the already complex perpetual calendar chronograph was so complicated to manufacture that only a small number of watches were delivered each year. Powered by the Nouvelle Lemania-based calibre that can be admired through the crystal case back, the reference was produced in a variety of metals (pink gold, yellow gold, white gold, platinum and stainless steel) during a 16-year run, from 1994 till 2010.

Not too small nor too large, the watch measures an elegant 36mm diameter and shares the aesthetics of the long lineage of perpetual calendar chronographs such as the reference 3970 and the iconic references 2499 and 1518. Yet, its stepped case is a little bit thicker and larger than its predecessors to accommodate the split-second complication, giving the watch a contemporary presence to the wrist. Displaying an oversized crown at 3 o’clock and an understated silver dial with applied Arabic numerals, the present platinum example exudes a potent mix of simplicity, modern aesthetics, and traditions; a winning combination to create one of the most desirable and versatile wristwatches.
