Seiko · Automatic
Overview
The Seiko Prospex SPB143 is a 2020 automatic dive watch, part of Seiko's '1965 Diver's Modern Re-interpretation' line that reimagines the historic 1965 62MAS diver. It pairs a compact, vintage-inspired stainless steel case (with Seiko's super-hard coating) and a charcoal-grey sunburst dial with the modern 6R35 automatic movement and its 70-hour power reserve. With a 40.5mm case, 47.6mm lug-to-lug, 200m water resistance, a 120-click unidirectional bezel, drilled lugs, LumiBrite, and a domed AR-coated sapphire crystal, it became a fan-favorite mid-range diver at its $1,200 launch price.
