The Seiko Prospex HBC002 reimagines the aesthetics of Seiko's legendary 1968 diver through a cleaner, more technical lens — sporting a bold black dial and a silhouette that balances athletic character with refined finishing.
Designed for those who want a serious professional GMT diver with a contemporary identity, this model delivers robust construction, advanced functionality and genuine wrist comfort, all rooted in Prospex heritage.
At its heart is the automatic Seiko 6R54 calibre with GMT function, allowing you to track a second time zone at a glance, backed by an impressive power reserve of approximately 72 hours. The 42mm case takes its cues from the 1968 icon and updates them with modern finishing and improved ergonomics.
