Abstract:

Three commercially available, Swiss made, submersible wrist watches, Rolex, Blancpain and Enicar, are comparatively evaluated and in turn are compared with the still-under-development standard USN watch Bulova. Specific features of the Swiss watches strap and second hand are recommended for inclusion in the USN watch. The Rolex watch is found to be not sufficiently waterproof, bearing out reports from the field and is recommended for deletion from the Navys approved list. The very cheap, but without rotatable ring, Enicar watch is found to be satisfactory, again bearing out reports from the field, and its inclusion on the approved list is recommended.
