The Grandmaster Chime, initial reference 5175, of which only seven pieces have been made (six for the best clients in the world and one for the museum) returns with a new reference and a new dial, but without all those incredibly elaborate engravings.

The wristwatch Patek Philippe more complicated than ever, it combines performance and elegance in a new 47.7 mm white gold version with two opaline blue dials on the front and back. The reversible case with pattern Clous de Paris hand guilloché is distinguished by its patented rotation mechanism.

Among the 20 complications there are five sound functions, two of which are patented worldwide: the acoustic alarm that sounds the preselected time and the repetition of the date that rings the calendar day at will.

The hand-wound mechanical movement is a real masterpiece and is the Caliber 300 GS AL 36-750 QIS FUS IRM which boasts over 1.500 components.

Features include: alarm isolation indicator and a second time zone. The day of the week, the date, arranged on two quadrants, the month and the leap year cycle are marked by a hand. The 4-digit year indication is, on the other hand, in a window. Price upon request.
