The Seiko Prospex SBEJ021 Diver Scuba 1968 Heritage GMT is a Japanese domestic boutique-exclusive model that elevates the iconic 1968 Prospex diver design with GMT functionality and a distinctly nuanced blue-gray dial with a contrasting gold GMT hand — inspired by light filtering through the ocean’s depths.

This watch is powered by Seiko’s Caliber 6R54, an automatic movement with manual winding capability, offering reliable timekeeping, an independently adjustable 24-hour GMT hand for tracking a second time zone, and approximately 72 hours of power reserve.

Housed in a robust stainless steel case with diamond-shield coating and a ceramic display bezel, the SBEJ021 delivers professional-grade performance with 200m water resistance suitable for diving and water activities. The dial is protected by a sapphire crystal with internal anti-reflective coating, while generous Lumibrite on hands, markers, and bezel ensures strong legibility in all lighting conditions.

Additional premium details include a screw-down crown, unidirectional rotating bezel, and one-push double-lock diver’s extender clasp — all hallmark features of Seiko’s Prospex diver lineup.

This model is exclusive to Prospex Concept Corners (Seiko boutiques, flagship salons, and online Japan store) and is distinguished as a specialty JDM (Japan Domestic Market) offering with a unique colorway.
