＜No Reproduction＞ ◾️Product Overview This is the PRT-3000, a full-metal model from Casio's Pro Trek outdoor watch series, released in 1998. (While the PRT-3000 also has a stainless steel model, this product is the titanium version.) It features a twin sensor for a barometer/altimeter and a thermometer, allowing you to understand weather trends from changes in atmospheric pressure and record altitude changes during movement. In addition, it has a full range of menus that could be measured and displayed on digital watches of the time, such as world time, stopwatch, and alarm. The biggest feature of this model is that it utilizes the casing technology cultivated in the G-Shock MRG series, a separate line, to achieve a full-metal construction. Both the body and bracelet are made of titanium, and the back cover has a screw-back structure for excellent airtightness. The cylindrical sensor installed on the left side of the body is an impressive design, asserting that it is not just a digital watch but an instrument. What I personally like is the shape of the titanium bracelet, with large and small links that are carefully chamfered and processed into a beautiful round shape, and its design and comfortable fit exceed expectations for a watch in this class. It has a very high-quality feel and high reliability as an industrial product, making it a vintage digital watch from the 1990s. ◾️Condition ・There are minor scratches due to use overall, but none are noticeable, and I think it can be said to be in good condition.
