The Nautilus in steel now dazzles with a new blue-to-black gradient dial inspired by the original 1976 model. The horizontally embossed dial, paired with a moon-phase display and Annual Calendar, exudes a refined yet sporty elegance. Underneath its 40.5 mm case lies the self-winding Caliber 324 S QA LU 24H/303, visible through the sapphire crystal case back. This timepiece features a blue dial with a black gradation and gold-applied hour markers, set within a robust steel case and secured with a patented fold-over clasp. Water-resistant to 30 meters, it seamlessly blends sophistication with functionality.
