Product Details
Seiko Prospex SPB143J1 is a modern reinterpretation of Seiko’s 1965 diver’s watch, combining vintage-inspired proportions with a robust stainless-steel case and bracelet, charcoal-gray dial and black unidirectional dive bezel.
The watch is powered by Seiko’s Caliber 6R35 automatic movement with manual winding capability, stop-seconds functionality, 24 jewels and approximately 70 hours of power reserve. A curved sapphire crystal with anti-reflective coating, screw-down crown, secure clasp with extender and 200-meter diver’s water resistance complete the specification.
