Description
The Seiko Prospex SPB509J1 is a bold tribute to 60 years of dive watch heritage, crafted for those who appreciate both function and story. Limited to just 6,000 pieces, it’s powered by the 6R54 automatic movement with a 72-hour power reserve and a handy dual-time display—perfect for travelers and adventurers.
The 42mm stainless steel case is paired with a ceramic bezel and a sapphire crystal that’s treated for glare-free clarity.
