Overview

The Patek Philippe 5146G-001 is a 39 mm white gold dress watch housing the manufacture's annual calendar complication alongside a moonphase and power-reserve indicator. Its slate grey dial, set with applied indexes, strikes a quietly authoritative tone that places it firmly within the grand tradition of Patek Philippe's Complications collection. The reference ran for roughly sixteen years, earning a reputation as one of the most wearable expressions of the annual calendar in the modern catalogue.

History

Patek Philippe introduced the annual calendar complication in 1996 with reference 5035, a mechanism requiring only one manual correction per year — at the turn of February into March. The 5146 family, launched in the mid-2000s, refined the concept into a slimmer, more classically proportioned case and added the moonphase and power-reserve displays driven by Calibre 324 S IRM QA LU. The 5146G-001, in 18k white gold with a slate grey dial, remained in production until 2021, spanning a period during which the annual calendar became one of the house's most recognised and collected complication families.

Notable points

Calibre 324 S IRM QA LU is a self-winding movement incorporating an instantaneous perpetual-style annual calendar, moonphase, and power-reserve indication on a single dial.
The annual calendar mechanism requires only one correction per year, advancing automatically through months of 30 and 31 days but needing a manual adjustment at the end of February.
At 39 mm, the 5146 occupies a dress-watch sweet spot — large enough for legibility, compact enough for formal wear under a shirt cuff.
The slate grey dial with applied gold indexes gives the 5146G-001 a distinctly contemporary character compared to the more traditional silver or champagne dials found elsewhere in the line.
Production spanned approximately 2005 to 2021, making the reference a long-running pillar of the modern Complications catalogue before its eventual discontinuation.
