Seiko has been crafting reliable, innovative timepieces since 1881, earning global respect for combining Japanese engineering with a deep commitment to craftsmanship. Their Prospex line continues Seiko’s legacy of professional-grade sports watches with serious dive credentials.

The Seiko SPB483 is part of a new generation of modern divers introduced in 2024, combining a bold geometric case design with everyday wearability. It builds on the brand’s decades-long dive watch heritage, but with a sleeker profile and a fresh design language that sets it apart from vintage-inspired models. Inside the 41.3mm case beats Seiko’s in-house Caliber 6R55 automatic movement, offering an impressive 72-hour power reserve. It’s rated to 300 meters of water resistance, features a screw-down crown, and is protected by a flat sapphire crystal with anti-reflective coating. The unique twelve-sided bezel adds a contemporary edge, while the rich blue dial and bezel insert offer strong contrast and clarity.
