Hei Matau Cave Diver Open Heart Blue Mother of Pearl Dive Watch

SKU: 10090
  • Aquacy Branded Genuine Leather 2 Watch Roll


    The Cave Diver is inspired by the record breaking, deepest cold water cave dive ever completed. The dive occurred in New Zealand in 2011. Divers reached a depth of 194M but still did not find the end of the cave or its mysterious source. Even dye tracing has been unable to find the source. The expedition was funded in part by National Geographic.
