Making sports watches in an elegant design is a mighty feat but, Patek Phillipe is always up to the task. The classic Nautilus reference 5711/1R-001 is full of refinement with its 40mm rose gold case with a screw-down crown and a sapphire-crystal case back. It has a fixed bezel made of rose gold and a rose gold bracelet with a Nautilus fold-over clasp. The dial is a brown gradated color with gold applied hour markers that have a luminescent coating. This timepiece runs on the self-winding caliber 324 SC with a date feature and a power reserve of up to 45 hours. It is water-resistant up to 120 meters (393 feet).
