The Seiko Prospex SBDC065 serves as a modern re-interpretation of the brand's foundational 1968 hi-beat automatic diver reference 6159-7001. The 44mm stainless steel case is notable for its faceted lugs and the use of Zaratsu-style polishing on its flanks, a finishing technique typically associated with higher-tier Grand Seiko models.
It is powered by the dependable calibre 6R15, an automatic movement with a 50-hour power reserve, and the case is protected by Seiko's proprietary DiaShield hard coating for scratch resistance. The SBDC065 is regarded as a significant reference for successfully bridging the gap between Seiko's entry-level divers and its premium "Marine Master" echelon.
Established in 1881 by Kintarō Hattori, Seiko is defined by its principle of complete vertical integration, manufacturing every single component of its timepieces in-house. They were the primary catalyst of the "Quartz Crisis" with the commercial release of the 1969 Astron—the world’s first quartz watch—the brand simultaneously advanced mechanical horology, developing one of the first automatic chronographs and pioneering high-frequency movements to challenge Swiss standards.
Seiko's relentless innovation continues with proprietary technologies like Spring Drive, which blends mechanical power with quartz precision. This technical mastery underpins Seiko's legacy in creating archetypal and exceptionally durable tool watches, particularly in the domain of professional diving.
