Seiko Prospex SPB147J1
This versatile timepiece reimagines Seiko's 1965 first diver's watch, an automatic timepiece with a then exceptional water resistance of 150 meters. Offering an extraordinarily legible dial and durable enough to become standard equipment on the Japanese Antarctic Research Expedition (JARE), this landmark timepiece propelled Seiko into the forefront of dive watch design.
