As such, it is of historic significance and naturally, one of the ultimate and most exclusive trophy watches of the reference. In addition to the signature ‘Cartier’ on the dial below the moon phase, the watch features the Cartier’s hand-stamped five-digit reference no. 17544 underneath the upper left lug.

Reference 1518 is not only the earliest Patek Philippe perpetual calendar chronograph wristwatch serially produced; it is the first produced by any manufacturer, ever. And ref. 1518 is the rarest. This particular combination of complications confirmed Patek Philippe’s pre-eminent position as the greatest watch brand in the world.
