Seiko Men's Prospex Sea GMT Green Dial Watch SPB381
$1,500.00
The Seiko Prospex SPB381J1 is a bold and highly capable GMT diver’s watch that reinterprets Seiko’s iconic 1968 diver heritage with modern engineering, refined finishing, and exceptional travel-ready functionality. Crafted in a 42mm stainless steel case with super-hard coating, this striking timepiece features a rich marine green sunray dial paired with a matching green ceramic unidirectional bezel and a gold-tone GMT hand for a sophisticated yet sporty aesthetic. Powered by Seiko’s in-house 6R54 automatic GMT movement with manual winding capability, the SPB381J1 delivers an impressive 72-hour power reserve and allows independent adjustment of the 24-hour hand for convenient dual-time tracking while traveling. Designed for serious underwater performance, the watch offers 200 meters of water resistance, LumiBrite hands and markers, a sapphire crystal with anti-reflective coating, screw-down crown, and a secure bracelet with diver’s extender clasp for enhanced durability and comfort. Combining robust dive-watch functionality with elegant finishing and practical GMT capability, the SPB381J1 stands as one of the most versatile and sophisticated models in the modern Prospex collection.
