The new Prospex re-creation of this 1970 diver’s watch is slightly larger than the original but faithful in every other respect to its design. It is, however, completely up-to-date in its technology. It incorporates caliber 8L35 which was specially designed for use in diver’s watches. The case has a super-hard coating and a dual-curved sapphire crystal with anti-reflective coating and is 200 meter water resistant. The upper surface of the bezel rim is Zaratsu polished to a perfect mirror finish. Presented on a high strength silicone strap, this Prospex timepiece is assembled by hand in the Shizukuishi Watch Studio in northern Japan.
