Introducing new night safari concept models for the lineup of Triple Sensor Version 3 PRO TREK models. The colors and designs of these three new models all were specially selected for the night time outdoor scene. The outside of the bands and the faces of all three models are black. The designs of these models are stylish and subdued, without sacrificing the readability required during night time activities. The PRG-650Y/650 models come with DURA-SOFT bands that incorporate silicon materials that improve durability. The inside of the band is luminescent, so it emits a faint glow during night activities. The PRG-650Y/650YBE models feature ion-plated bezels. Function-wise, all three models are equipped with Neon Illuminator to provide easy reading of the time and function modes, even in the dark. Other basic functions include Triple Sensor (bearing, altitude/barometric pressure, temperature), one-touch measurement button, Tough Solar, and more. Movable lug components add to a better fit and more comfort. Everything about these models is designed and engineered to create functions and designs for night time outdoor activities. • Smart Access with an intuitive electronic crown switch, and independent multi-motor drive of hour, minute, and second hands for smoother operation • Tough Solar • Triple Sensor (bearing, altitude/barometric pressure, temperature) • Barometric pressure graph • Barometric pressure alarm • Low-temperature resistant (–10℃/14℉) • Luminescent band and hour markers
