The 5140P-013 has been in the collection since 2006 yet this iteration must surely be the most attractive so far. An ultra-thin perpetual calendar moon phase based around the famous self-winding calibre 240 Q, now with a luscious ebony black sunburst dial. The dial uses diamond dot hour markers including a pair of baguette diamonds at the 12 o'clock position. As usual with gents platinum watches, Patek have carefully set a diamond in the case out of sight. Timeless.
