Seiko Luxe Prospex Marinemaster 1968 Heritage JAMSTEC Limited Edition Diver's Blue Dial Blue Bezel Stainless Steel Bracelet 42.6 mm Automatic Watch - HBF002
SEIKO LUXE
Seiko’s legacy of testing the limits of the modern sports watch and supporting marine conservation continues through its partnership with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), which began in the 1980s. In 1983, two professional diver’s watches rated to 600 meters were successfully tested aboard the SHINKAI 2000, a manned research submersible which was operated by JAMSTEC. Inspired by the spirit of bold exploration that connects JAMSTEC and Seiko, a new limited-edition diver’s watch joins Prospex’s flagship Marinemaster series. The Japan Agency for Marine-Earth Science and Technology (JAMSTEC) is a national institute for comprehensive marine research and development dedicated to advancing innovative science and technology. JAMSTEC fosters academic progress and deepens understanding of the Earth and life, while contributing to the sustainable development of society and the preservation of the global environment. Using data obtained through its research, JAMSTEC strives to address societal and economic needs and drive innovation across multiple sectors. The dial’s new three-dimensional pattern takes inspiration from the tracks carved through sea ice by icebreaking vessels. Its blue gradient, which deepens toward the center, combines with a thick, transparent coating that is meticulously polished to create exceptional clarity and depth. Together, these elements evoke the pure, profound blue that emerges within the Arctic Ocean, revealed amidst the vast expanse of drifting sea ice. The design features a blue ceramic bezel that enhances the beauty of the dial while providing exceptional scratch resistance. With Caliber 8L45, Seiko has improved the shape and design of the mainspring and implemented precise accuracy adjustments, achieving the highest accuracy (-5 to +10 seconds per day) among Seiko’s current mechanical movements and a power reserve of approximately 72 hours.
