Patek Philippe Tiffany and Co

Feast your eyes on the Tiffany Blue Patek Philippe 5711, a limited-edition twist on watchmaking's most-coveted steel reference. The latest 5711 feels as much a Tiffany product as it does a Patek Philippe.

The blue really announces itself. That Patek chose to share the spotlight with a partner in such an intimate way as it closes the ledger on a crucially important product says something about how the executives running the august Geneva firm view their business relationships.
