Up for sale is a NOS Rare Vintage Casio Pro Trek Thermometer PRL-10 men’s digital sports watch from the 1990s, produced for the Japan Domestic Market (JDM) and powered by module 1646. This early Pro Trek model reflects Casio’s push into outdoor instrumentation watches during the era, combining rugged digital functionality with built-in environmental sensing technology.
The watch is in full working condition and all features and functions of the watch are working properly, including the integrated thermometer function.
All parts of the watch are original, and the watch comes with its original box and original hang tag.
The watch shows signs of handling and storage wear from many years of storage, but the photos best describe its physical condition.
