Casio Protrek - PRW-30-5
Features
An array of large metal buttons on the right provide one-touch access to compass, barometric pressure/altitude, and temperature readings that appear on the LCD. Icons on the face glass next to each of the buttons contribute to easy-to-understand, intuitive access to the information you need even when facing a severe outdoor environment. The digital LCD uses a high-contrast bold font, which, in combination with an STN LCD, ensures improved visibility even under harsh sunlight.
Other functions include Tough Solar, time calibration signal reception, and 100-meter water resistance, all of which help to ensure you get the timekeeping performance you need under harsh conditions. In addition to all of this, these models boast smaller cases and a thinner looking bezel. The watches are designed so they do not interfere with wrist movement while engaging in mountain climbing, camping, and other outdoor activities. These models come with DURA-SOFT bands that incorporate silicon materials to improve durability. The fit of these watches has been improved to support comfort during longer mountain climbing and other outdoor sessions.
These models pack all the function of triple sensors and an easy-to-read digital display into an amazingly compact configuration.
