The Nautilus 5712R-001 combines the distinctive porthole-inspired design of the Nautilus collection with an elegant 18K rose gold case and refined leather strap. Its sophisticated black-brown dial features the collection's signature horizontal embossed pattern and an asymmetrical arrangement of the complications. The ultra-thin self-winding Calibre 240 PS IRM C LU provides a pointer date, moon-phase display, power-reserve indication and small seconds. The movement features a 22K gold off-centre micro-rotor and approximately 38–48 hours of power reserve.
