Details

The SPB483J1 brings together the functionality of a sports watch with the refined elegance of a dress timepiece, making it a versatile addition to any collection. Beneath a scratch-resistant sapphire crystal glass sits a striking cobalt blue dial with a calm coastline-inspired pattern. The matching blue polygonal-style bezel features gentle curves that add a modern aesthetic while providing enhanced grip for smooth, comfortable rotation.

Designed for clarity and durability, the hands and indices are generously coated with Lumibrite to ensure excellent visibility in low-light conditions. A super-hard coating protects the case from scratches, while mirror-finished surfaces give the watch its refined sheen. Built to professional ISO diving specifications, this model transitions effortlessly from formal settings to active environments.

At its core, the SPB483J1 is powered by Seiko’s reliable in-house 6R55 automatic movement, delivering an accuracy of -15/+25 seconds per day and a three-day power reserve. With water resistance up to 300 metres, this Prospex timepiece reflects Seiko’s commitment to professional specifications, durability and performance for sports lovers and adventure seekers alike.
