The Seiko Prospex HBC001J1 combines adventure-ready functionality with Japanese precision, featuring a bold GMT design created for explorers who travel across time zones.

Powered by Seiko’s automatic Calibre 6R54 GMT movement with a 72-hour power reserve, sapphire crystal, and 200 m water resistance, this timepiece delivers exceptional performance on every journey.

Built with Seiko’s renowned craftsmanship and a rugged stainless steel design, the Prospex HBC001J1 is a versatile companion for global adventures, everyday wear, and beyond.
The green dial with matching green bezel reflects the heritage design of the 1968 Diver’s GMT from the Prospex Sea collection.
The watch is powered by the Calibre 6R54 automatic movement with manual winding, stop second hand function, 24-hour hand for dual time display and approximately 72 hours of power reserve.
The stainless steel case with ceramic bezel insert is paired with sapphire crystal with anti-reflective coating, stainless steel bracelet, LumiBrite on the hands, indexes and bezel, and 300 m water resistance.
As part of the Prospex Sea collection, this watch combines diving functionality with GMT timekeeping and the design heritage of Seiko’s 1968 Diver’s watch.
At CIRCA, we love this watch for its heritage diver design, GMT movement, and Prospex Sea functionality built for diving.
