PATEK PHILIPPE, YELLOW GOLD PERPETUAL CALENDAR, REF. 5059J

Patek Philippe introduced the reference 5059 in 1998. This model possesses an intriguing complication: a retrograde date display. The date is indicated by a hand progressing along a 240 arc located within the hour scale between 8 and 4 o'clock. Around midnight on the last day of each month, be it the 28th, 29th, 30th, or 31st, the hand automatically jumps back to the 1st. The reference 5059 was discontinued in 2006 and replaced by reference 5159.
To the best of our knowledge this watch has never before been offered in public.
