Patek Philippe introduces a new function that enriches its calendar watches: the “seven-man” calendar, a semi-integrated mechanism that indicates, in addition to the day of the week and the date, the number of the current week. A very useful feature for today's career men.

Il Calatrava Weekly 5212A-001 with a 40 mm steel case, it also houses a brand new automatic movement that boasts optimized performance. The dial is distinguished by the exclusive numbers and letters reproducing a handwritten handwriting.

The weeks are numbered according to the standard ISO 8610., according to which the first full week in any year must start on Monday and not Sunday, just as the first full week of the year is the one that contains January 4th. A feature of this standard is that occasionally a year will contain 53 instead of 52 weeks, which is explained in the calendar mechanism and numbering scheme made on the specially based dial and drawn on the handwriting of one of the brand's watch designers.

The self-winding mechanical movement is the Caliber 26-330 SCJ SE. On the opaline silver-colored dial, the indexes are applied in burnished gold, the day and week number are displayed by hand, while the date is in a window. Central to the seconds. Price 30.860 EURO.
