Patek Philippe Nautilus Moon Phase 5712/1A-001 | Dark Blue-Black Tiffany & Co. Double Signature

The moon-phase, power-reserve and calendar indications keep their familiar off-center arrangement. A dark blue-black gradient gives those displays a restrained field; the Tiffany & Co. double signature at six provides the distinction for a collector who wants a specific dial treatment rather than a brighter color.

Integrated steel links continue the Nautilus case line around the wrist. The updated push-button folding clasp adds adjustment without changing the front-on character, while the Caliber 240 layout keeps the case comparatively slim for a multi-display watch.

This is a dial-detail choice within the 5712 family. The Tiffany & Co. double signature sits at six against a dark blue-black gradient, so it remains recognizable without turning the whole face turquoise. The off-center moon phase, reserve and calendar keep their familiar visual rhythm. The blue-grey sibling offers the same family in a quieter presentation without that signature. For a collector who already knows the 5712 arrangement, the signed dial supplies a clear reason to choose this version, while the steel bracelet and folding clasp preserve the familiar wearing format.
