Patek Philippe Grand Complications 5139G-001 | 18K WG | Grey Dial

The Ultimate Heirloom of the Maison

Patek Philippe reference 5139G-001 stands within the Maison’s Grand Complications as a sober and noble expression of timeless mastery. Though the listing is economical with technical detail, the reference historically belongs to Patek’s line of perpetual calendars—an instrument that codifies astronomical time into an eternally accurate calendar, most often accompanied by a moon‑phase display and driven by an automatic micro‑rotor calibre.

The Hallmarks of a Historic Lineage

• Reference Number: 5139G-001
• The Signature Complication(s): Perpetual Calendar with Moon‑phase (designation implied by the reference and by its place in Patek’s Grand Complications; the listing itself does not enumerate the sub‑indications)

• The Calibre’s Lineage: Automatic micro‑rotor heritage typical of Patek perpetual calendars (calibre number not specified in the listing; models of this class commonly house a calibre descended from the 240 Q line)
• Case Material and Dimensions: 18k White Gold, 38 mm
• Dial and Bracelet: Grey dial (listing); bracelet options noted as 18k white gold or alligator leather
• Includes: Box and Papers (complete provenance as offered)

The Curator’s Insight:
To steward a perpetual calendar from Patek Philippe is to accept custodianship of a machine that measures civil and celestial time with rare, centuries‑spanning accuracy; integrating such a mechanism into a 38 mm white‑gold case demands the quiet genius of generations of master watchmakers.

A Timepiece to be Stewarded for History

This 5139G-001 is less an accessory than a compact archive of horological achievement—an object whose value is measured as much in legacy as in material. Presented in white gold with a refined grey face, it is a watch meant to be preserved, studied and passed down: an heirloom that accrues not only monetary worth but historical and familial significance.
