The SPB455, part of the trio launched for Seiko's special centennial, is a diver's watch designed with subtle yet impactful upgrades that enhance both its aesthetic and technical appeal. It features a 40mm case diameter, a 46.4mm lug-to-lug length, and a slim 13mm thickness, making it compact and wearable without sacrificing presence on the wrist. The stainless-steel case is paired with a slim, unidirectional aluminium bezel, colourmatched to the dial, and laser-engraved minute markers for longevity. Under a flat sapphire crystal dome sits the charcoalgrey sunburst dial, accented by satisfyingly chunky and rectangular gold hands and markers, a nod to Seiko's long history of watchmaking advancements.
