Patek Philippe 5146J-010 Annual Calendar Moonphase 18K Yellow Gold Gray Dial

The Patek Philippe 5146J-010 is a masterclass in refined complication, marrying an annual calendar with moonphase and power reserve indicators in a compact 39 mm 18K yellow gold case. Powered by the automatic Caliber 324 S IRM QA LU, this movement delivers approximately 45 hours of power reserve and showcases Patek’s technical excellence through its sapphire exhibition caseback. The slate gray sunburst dial, with applied yellow gold baton and Arabic markers, offers exceptional legibility and a timeless aesthetic. Introduced in the 2010s, this reference continues the lineage of Patek’s annual calendar tradition, offering collectors both historical significance and daily practicality. Its 11.2 mm thickness ensures a balanced wrist presence, while the 30 m water resistance underscores its dress watch refinement rather than sport utility. The watch is fitted on a hand-stitched alligator strap, complementing the warm tones of the gold case and enhancing its elegant profile. As a complication-driven dress piece, the 5146J-010 stands out for its harmonious integration of functions, movement pedigree, and enduring design — a compelling proposition for discerning collectors.
