Casio PROTREK PRT-B50-1JF Manufacturer Maintained

Casio PROTREK PRT-B50-1JF, manufacturer-maintained. Purchased new and used occasionally. As I own other watches, this unit has seen infrequent use and is in relatively good condition.

On July 28, 2023, battery replacement, band replacement, and waterproof testing were performed by Casio Techno Co., Ltd. It has not been used since then. While the manufacturer states a battery life of 2 years, this one lasts approximately twice as long. Although there is minimal signs of wear, the original band will be included.

This model from PRO TREK enhances outdoor usability through connectivity with the dedicated CASIO WATCHES app via Bluetooth®.
It features a Quad Sensor that enables measurement of direction, altitude/barometric pressure, and temperature, in addition to step counting. It records calories burned and the route obtained from the watch's altitude data and the smartphone's GPS in the app. Automatic time correction is possible worldwide by simplifying various settings. Furthermore, it can automatically correct altitude readings and calculate sunrise/sunset times.
Modes can be turned on/off and displays can be switched within the app, allowing for customization.
The fine resin case back adopts a structure integrated with the lugs. Along with the button guard, the case's robustness is also enhanced. The wide dial uses Arabic numerals for high visibility. The bearing indicator uses metal parts, accented with outdoor-themed colors. Additionally, the urethane band features a full 3D texture, preventing the keeper from slipping and improving usability in outdoor scenes. The retail price was ¥33,000.
