Analogue and Digital Time Displays for Military Wristwatches.

Abstract

The RAAF currently uses wristwatches with analogue (conventional clockface) displays. In response to a RAAF request, the arguments for and against using digital display wristwatches for military use were examined and an evaluation of two related US documents was carried out. One document, a US military specification for liquid crystal display digital wristwatches, includes most of the necessary safety and operational considerations. The other document, a questionnaire evaluation of military digital watches, appears somewhat unjustifiably biased in favour of digital wristwatches. It is recommended that for RAAF use, the US military specification should not be used in its present form as it leaves insufficient scope for technological improvements. Attention is drawn to alternative designs/displays for wristwatches, for example combination digital-analogue watches and electrochromic display watches. (Author)
