As we mentioned in our Introducing post for this watch, it is not a reissue of the Willard 6105 (which, by the way, is also sometimes referred to as the “Uemura Diver,” after the Japanese polar explorer Naomi Uemura, who also wore one on his solo expedition to the North Pole) although it’s enough like the original that if you saw it on someone’s wrist on a dark night, or in the gloom of the jungle primeval, you could easily mistake the new for the old. Where the new model differs from the original, aside from being new, is in size, fit, finish, and in the use of better components and materials, especially the movement.
