The original model was introduced to meet the needs of mountain climbers and recreational field sports enthusiasts. It had a screw back to prevent dust and sand from entering the case and a sturdy leather cuff strap to protect the watch from perspiration. The luminous indexes and hour and minute hands ensured high legibility in the dark. This feature became central to the design of many subsequent Seiko sports watches and remains so to this day.
