Patek Philippe World Timer

The Patek Philippe 5231J is a rare display of craft, detail, and world-class finishing. This 2021 example features the famed cloisonné enamel dial, framed in yellow gold, on a blue leather strap. It comes as a full set—box, papers, certificate, and gold deployant clasp. The condition is very good, with signs of careful wear.

The 38.5mm case is crafted from polished 18ct yellow gold. It has a slim profile and short curved lugs. The case is dress-weight, easy to wear, and built to exact standards. The world time pusher sits at 10 o’clock. The crown and deployant clasp are signed. The bezel is rounded and soft, with a mirror finish all around.

The dial is hand-made cloisonné enamel, depicting Eurasia, Africa, and Asia. Each section is separated by fine gold wire and fired in layers. The tone is rich, the detail sharp. Around the enamel map are 24 city names, one for each global time zone. The outer ring tracks the 24-hour scale in day and night segments. The local time is set at 12 o’clock.

There is no date. No sub-dial. No excess. Just world time in full mechanical clarity. The central hour and minute hands are made from yellow gold and point cleanly over the map. Time zones are changed instantly using the pusher, which jumps the hour hand and city ring forward in sync.

Inside is the Patek Philippe Calibre 240 HU. It’s a micro-rotor movement with a 48-hour reserve. It’s slim, quiet, and finished to Geneva Seal standards. The movement is visible through the sapphire caseback. The bridges are hand-finished, the rotor engraved, and every edge chamfered by hand.

The strap is dark blue leather with a matching yellow gold deployant clasp. It’s in very good condition, showing light wear on the underside but no cracking or stress. It fits the case perfectly and sits comfortably on the wrist.

This 5231J is in very good condition. There are minor hairlines on the case and clasp, but no deep scratches or dents. The enamel dial is flawless. The watch runs perfectly and has been fully verified.

The Patek Philippe 5231J is a true collector’s piece. Elegant. Historic. And almost impossible to fake. This full set from 2021 is serious—complete, correct, and ready to go.
