SPB451J1 brings a clear point of view to Seiko's Prospex Sea collection, led by a blue dial and a 40.0 mm stainless steel case. SPB451J1 uses curved sapphire crystal above the dial and a stainless-steel bracelet at the wrist, keeping the exterior materials visually connected.

SPB451J1 is powered by an automatic movement with manual winding, built around caliber 6R55 with approximately 72 hours / 3 days of power reserve; water resistance is rated at 300 m / 1000 ft. SPB451J1 pairs a serious dive-watch foundation with enough visual control to remain useful well beyond the water.
