Inspired by the vast depths of the ocean and created in collaboration with PADI, the Seiko Prospex SPB375J1 “Great Blue” Special Edition brings together rugged functionality and striking marine aesthetics. Nicknamed the “Sumo” by fans for its bold silhouette and oversized case, this diver's watch features a 45mm stainless steel case with a super-hard coating, ensuring enhanced scratch resistance.

With its vivid oceanic dial, sapphire crystal, and unidirectional rotating bezel, the SPB375J1 is engineered for both professional and recreational divers. The screw-down crown and case back ensure a secure 200m water resistance, while the “Special Edition” engraving on the case back marks its exclusivity. A true testament to Seiko’s dedication to diving excellence.
