The digital display shows the best fishing times (FISH IN TIME) for a specified location and date, along with fishing probability. The watch sounds an alarm when a fishing time is reached, and the second hand counts down the time from FISH IN TIME start to the end.

Tide Graph, Moon Data, Sunrise and Sunset Times

Tide information, Moon age, and sunrise and sunset times can be displayed for a specified location and date. This lets you get an idea of your expected catch during a specific time frame and helps you to better plan your fishing activities.

Quad Sensor

Quad Sensor capabilities let you measure direction, barometric pressure and altitude, temperature, and your step count. Barometric pressure measurement and other data help you get a grasp of fishing conditions at your current location and plan your daily activities.

200 Meter Water Resistance

A fine resin case ensures the high level of toughness and airtightness required for fishing and other water activities.

Hand Shift

Hand shift momentarily moves the hour and minute hands out of the way for easier reading of digital display information.

PRO TREK Connected

PRO TREK Connected

After installing the PRO TREK Connected app on your phone, you can link with the watch and automatically adjust its time setting.
Phone linking simplifies a number of operations, including FISH MEMO record management, quick access to the current time in 300 cities around the globe, and time setting configuration.

Fishing Point Setting

You can specify any one of approximately 3,300 points at ports around the world. Simply select a port on a map to access fishing times, Tide Graph information, Moon data, and sunrise and sunset times for that location.


Watch button operations can be used to record your current fishing location, time and date, and conditions with the phone app. For each point displayed on the map, you can check the barometric pressure tendency, tide information, and FISH IN TIME information. You can even add FISH MEMO records and images. Date and time information and other data can be exported (GPX format) and shared with your friends.

• Tide information and FISH IN TIME information is the data for the fish point selected with the app.

Calories Burned

Altitude measurement and the step count are used to calculate and display the calories you burn, and record the data in an activity log.

300-city World Time

Simple phone operations can be used to configure World Time settings. You can select one of 300 cities by touching the one you want on a world map or a city list.

Location Indicator

The press of a watch button registers your current location with the phone app. After that, the watch’s second hand will indicate the bearing back to the registered location, while the digital display shows the distance to the location.

Mode Customization

The phone app can be used to enable or disable the display of specific modes, and even the sequence in which modes appear. You can configure settings so only the modes you use are displayed, or to cause the modes you use the most to be displayed first. You can also customize what information appears on the watch’s digital display.

Auto Time Adjustment

The watch automatically connects with your phone and adjusts your Home Time and World Time settings four times a day. If you travel to a different time zone, you can adjust your current time setting with the press of a button.

Accurate Time System

The watch adjusts its current time zone, summer time setting, and current time settings based on the time (UTC) and location data it obtains from an on-line time server via your phone.

Phone Finder

The touch of a watch button causes your phone to sound a tone.
