PATEK PHILIPPE, WHITE GOLD ANNUAL CALENDAR, REF. 5146/1G

Introduced in 2005, reference 5146 (39mm) replaced the reference 5035 (37mm), featuring a moon phase display instead of the 24-hour indication and a power reserve. Fitted with the patented annual calendar mechanism, this useful complication automatically corrects the date for months with 30 and 31 days while displaying the month and the day of the week and only requires correction once a year at the end of February.

To the best of our knowledge this watch has never before been offered in public.
