Patek Philippe Calatrava Ladies 4858G Silver Dial

Opening Context
Reference 4858G belongs to a particularly elegant chapter in Patek Philippe’s ladies’ watchmaking. Introduced in 1998 and produced until 2006, the 4858 was the Maison’s first ladies’ wristwatch to feature a moonphase display, placing a traditional complication within a compact, jewellery-led Calatrava format.
In white gold, the design becomes especially restrained. The 29 mm case is framed by a diamond-set bezel, while the silver guilloché dial and diamond hour markers give the watch texture and light without overwhelming its proportions.

Why This Reference Matters
The 4858G is distinctive because it treats the moonphase as part of the overall composition rather than simply an added complication. Small seconds and the moon display occupy the lower portion of the dial, while the engine-turned centre and diamond markers give the otherwise classical layout a more decorative character. Archival examples confirm the use of 12 diamond hour markers and a diamond-set white gold case.
Inside is the manually wound Calibre 16-250 PS LU, also catalogued in major auction records as Calibre 16-250/161. The 18-jewel movement runs at 28,800 vibrations per hour and offers approximately 38 hours of power reserve.
Manual winding feels particularly appropriate here. It keeps the watch mechanically traditional while allowing the case to remain compact and elegant.

On the Wrist
At 29 mm, the 4858G wears with true classical ladies’ proportions. The diamond-set bezel gives it more visual presence than the diameter suggests, while the white gold case keeps the overall effect cooler and more discreet than the yellow or rose gold versions.
The silver guilloché dial changes subtly with the light, and the diamond hour markers add definition without making the watch feel overly ornate. On a white leather strap with white gold pin buckle, the watch takes on a lighter, more contemporary character while retaining its fundamentally traditional proportions.
It is small by modern standards, but intentionally so; the appeal lies in delicacy rather than scale.

Condition & Transparency
This example is presented on a white leather strap with an 18K white gold pin buckle. Specific information regarding case condition, polishing history, diamond condition, dial and hand condition, crystal, strap originality, box and papers, and previous servicing has not been provided. These details should therefore not be assumed. The calibre is commonly described as 16-250 PS LU, while Patek Philippe auction documentation also records the movement as 16-250/161; the exact engraving on the individual movement can be confirmed if required.

Why It Belongs in a Collection
The 4858G suits a collector who appreciates Patek Philippe’s complicated watchmaking in a smaller and more jewellery-oriented form. Its significance is not only aesthetic: as the Maison’s first ladies’ moonphase wristwatch, it occupies a meaningful place within Patek Philippe’s modern design history.
Within a broader collection, it offers something very different from a sports watch or larger complication. The manually wound movement, compact white gold case and moonphase display create an experience centred on refinement and detail rather than presence or technical spectacle.

Closing
The Patek Philippe Calatrava 4858G combines traditional mechanical watchmaking with an unusually delicate presentation. Its 29 mm white gold case, guilloché dial, diamond setting, moonphase and manually wound calibre give it both historical interest and considerable charm. For collectors comfortable with genuinely classical proportions, it is a particularly graceful expression of Patek Philippe.
