The 5320G is Patek's vintage-style perpetual calendar built for pure legibility — an in-line double day/month aperture sits at 12, while the date reads by hand around the moon phase at 6, a layout that keeps four calendar functions instantly readable without any visual competition. The rose-gilt opaline dial pairs with charcoal gray hour markers and hands, a contrast that's become something of a signature across Patek's vintage-inspired references, and the monobloc case's sharp three-tier lugs are entirely hand-polished rather than machine-finished.
At 40mm and 11.13mm thick, the case's height is kept in check by a convex "box" sapphire crystal, a period-correct detail that lets the profile stay lower than a flat crystal would allow at this diameter. The shiny chocolate brown alligator strap with square scales closes on a matching white gold fold-over clasp.
The calibre 26-330 S Q packs a full perpetual calendar — day, month, leap year, day/night, moon phases — into 368 parts and 29 jewels, finished throughout to the Patek Philippe Seal with a Gyromax balance, Spiromax balance spring, and 21K gold central rotor. Brand new, February 2025, full set.
