Notes

Introduced in the late 1990s, the Reference 5055 became one of the most distinctive members of the Calatrava family, its asymmetrical dial layout offering a poetic departure from traditional symmetry. The combination of power reserve indicator, date aperture, subsidiary seconds, and charming moonphase display reflects Patek Philippe’s mastery in blending mechanical sophistication with aesthetic elegance.

Rendered here in 18K white gold, the watch presents a striking contrast between the polished case and the deep black dial, punctuated by white numerals. The automatic calibre 240, with its off-center micro-rotor, ensures exceptional thinness while maintaining the brand’s exacting standards of finishing.

A subtle yet expressive timepiece, the Ref. 5055G stands as one of Patek Philippe’s modern classics, a watch where poetry, precision, and quiet distinction converge.
