The Patek Philippe references 4934 and 7134 represent two generations of the manufacture's ladies' World Time collection, combining one of Patek Philippe's most iconic complications with elegant proportions designed specifically for smaller wrists. Introduced in the early 2000s, the reference 4934 brought the celebrated World Time mechanism into the ladies' collection, powered by the automatic Calibre 240 HU. Its beautifully balanced dial, featuring a central guilloché medallion surrounded by rotating city and 24-hour rings, paid tribute to the historic World Time watches inspired by Louis Cottier while maintaining the refinement expected of a ladies' Calatrava.

The reference 7134 succeeded the 4934, retaining the ultra-thin Calibre 240 HU while introducing a more contemporary case design, slimmer bezel and revised dial aesthetics. Produced in white gold and rose gold, the 7134 refined the original concept with improved legibility and a lighter, more modern appearance, while preserving the elegance and practicality of the World Time complication. Together, the 4934 and 7134 illustrate Patek Philippe's commitment to offering sophisticated complications within its ladies' collection, demonstrating that the manufacture's most celebrated mechanical innovations are presented with the same technical excellence and timeless design regardless of case size.
