Patek Philippe 5146G-001 presents a complete annual calendar configuration within a white gold case, combining multiple functional displays across a balanced dial structure. The watch features apertures for day and month, a central date indication, and a subdial incorporating both moon phase and power reserve information. This multi-layered layout allows the wearer to monitor both calendar progression and movement status simultaneously. The Caliber 324 S IRM QA LU powers the watch, offering consistent energy distribution and reliable complication management.

This movement is constructed to maintain stable amplitude while driving several calendar functions, ensuring precise transitions at each cycle. The inclusion of a power reserve indicator provides an additional level of control for the user, while the moon phase display is calibrated for long-term accuracy. The white gold case contributes to a more understated aesthetic, emphasizing precision over ornamentation. The 5146G-001 stands as a technically complete annual calendar with expanded functionality.

Historical movement note: The earliest 5146 examples from the model’s 2005 introduction can be encountered with the earlier Calibre 315 S IRM QA LU, while later 5146G-001 examples are documented with Calibre 324 S IRM QA LU. Therefore, the reference number alone does not always identify the movement generation of an early-production example.
