1958
Prickett, C. | Wheat, J. L. | Searle, W. F.
Three preproduction samples of a BULOVA submersible wrist watch manufactured under BuShips contract in accordance with MIL-Ships-W-2181 are evaluated. Watertightness, readability-in-darkness and various subjective tests are reported. The specified test depth is 392 feet (175 psi), held for one hour. The watch face includes a moisture color-indicator and also a control color patch and change in color has been used as an acceptance criteria for watertightness. Two of the three watches indicated moisture, one during testing and the other several days after testing. No water or moisture was noted in the case. Readability of the watch in darkness, underwater, was satisfactory with the exception of the second hand which was too thin to be seen. Several physical improvements are recommended as a consequence of subjective evaluation. The watches are not recommended for acceptance in that the specified watertightness test has not been met.
