This limited edition model takes inspiration from the colossal ice planet, "Neptune," named after the Roman god of the sea. A distinguishing feature of this design is the inaugural use of a sapphire bezel with a full vapor-deposited coating. The profound azure radiance accentuates the allure of sapphire. Constructed from luminous and translucent Duratect Platinum, both the case and the band exude a sense of cleanliness and divinity. Reduced coloring in yellow gold is applied to the indexes and hands, further enhancing the overall aesthetic. On the case back, a depiction of Neptune wielding a trident and a cascading stream of water is engraved, mirroring the origin of Neptune's planetary symbol "♆."
