Now, the brand is revisiting one of its most iconic timepieces with the Limited Edition Prospex Marinemaster 1968 Heritage Diver’s Watch. But despite spending more than a decade designing watches, Kawamura says the most rewarding part of his work goes beyond creating timepieces. The collection features two models — the HBF001J Marinemaster 1968 Heritage Diver’s Watch and the limited-edition HBF002J Marinemaster 1968 Heritage JAMSTEC Limited Edition. By merging polar exploration with Seiko’s diving heritage, the latest Marinemaster models continue the brand’s tradition of creating timepieces inspired by the environments around them. It carries Seiko’s heritage while taking on new meaning through the people who wear it.
