Consigned by the original owner, the present watch is offered in excellent condition and comes with all its accessories. The reference 5975 multi-scale chronograph was made as special limited edition to celebrate the 175th anniversary of the Geneva firm. Of the 1,300 made, 400 were produced in yellow gold, pink gold, and white gold and 100 in platinum. This was the first automatic chronograph-only wristwatch ever made by Patek Philippe, furthermore it was the first made without chronograph registers or even a subsidiary seconds dial.
The watch is characterised by three different timing scales: a tachymeter, for calculation of speed over a known distance; a telemeter for determining distance based on a calculation between the speed of light and the speed of sound and a pulsometer, for measuring heartbeats per minute.
Following firmly in the tradition of Patek Philippe's best mid-century vintage chronographs, the dial of the 5975 is a masterful piece of design, managing to remain understated and elegant despite its complexity. The 40 mm. stepped case is superbly rendered with sharp angles and a solid caseback, engraved "175è Anniversaire 1839 - 2014", previously unseen on references with complications delivered after the early 1980s.
Fitted with the Caliber 28-520 stamped with the Patek Philippe Seal, attesting to its impeccable precision and finishing, the precision of the caliber was increased especially for the 5975.
