Sieko Nautilus Blue Dial

The 40mm 316L stainless steel case features brushed and polished finishes and a scratch-resistant sapphire crystal for durability. Its porthole-inspired design and textured dial create a refined, eye-catching look, while luminous hands and markers ensure visibility in any light.
