Introducing the special collaboration model of NANGA x PRO TREK

The collaboration model “PRW-6630NA-1A3DR” with the authentic outdoor gear “Protrek” for those who love nature and NANGA, a Japanese down maker, is now available.

Since both PRO TREK and NANGA are promoting initiatives that consider the natural environment, the watch body uses environmentally friendly biomass plastic for the case, band, and back cover. In addition, a limited eco bag with the NANGA x PROTREK logo printed on it is produced and included as a bundled item, and can be used as a luggage bag for everyday shopping and outdoor activities.

As for the design, by incorporating the design elements of a somewhat retro and traditional mechanical watch into the Pro Trek, which is packed with the latest technology, it has become an excellent design as a fashion item in the city. The theme color is ”OLIVE GREEN x COYOTE”, which is a color scheme that imaged adventure and environmental consideration, which is popular among NANGA products. It features a high design that can be used not only for outdoor scenes but also as a fashion item. The NANGA logo is applied to the dial, back cover, and play ring, and it is a limited special specification unique to collaboration.

Functions include a triple sensor that can measure direction, atmospheric pressure/altitude, and temperature with a single push, multiband 6 that supports standard radio waves from 6 stations around the world, and highly practical features such as tough solar that stably drives various functions. Prepare. Supports various activities with a full auto light that automatically turns on just by tilting your arm in the dark.

Introducing a collaboration model between the Japanese brand NANGA, which is particular about quality and safety, and the authentic outdoor watch PRO TREK, which continues to evolve as a gear for those who love nature.

PRO TREK,
now with eco-friendly
biomass plastics

The PRO TREK brand stands for experiencing, enjoying, and preserving the wonders of nature.
Now available in a new model that uses eco-friendly biomass plastics in the case, band, and case back.


Biomass Plastics

Biomass plastics are polymers produced using chemical or biological synthesis of materials sourced from plant matter or other renewable organic substances. They are widely thought to help reduce environmental impact and promote the shift to a circular economy. PRO TREK employs biomass plastics that are made from materials extracted from castor seeds and corn.


 

First Casio watch to use biomass plastics:

Delivering uncompromising durability and comfort.

For the first time in a PRO TREK or any Casio watch, the case and band are made from eco-friendly biomass plastics instead of conventional resins. The use of biomass plastics also delivers uncompromising resistance to hard use as well as comfort on the wrist. We are proud of this new material application for our line of premiere outdoor tools, PRO TREK.

Case back

Case back made from biomass engineered plastics

For optimal wear resistance and an airtight seal, the case back is made from high-strength engineered plastics made from biomass materials. The case back has a wider flat surface, as well, for better torsional resistance.

High-contrast dial

Dial contrast has been enhanced by using vivid white for the large bar indexes and hour and the minute hands, delivering optimum visibility in the field. The stainless steel bezel is engraved with city codes for an outdoor gear look.

Compact design never impedes movement

The smaller design never impedes wrist movement in the outdoors, while delivering uncompromising dial visibility and ease of use.

  • WATER RESISTANT (10 BAR)

    The “BAR” value indicates the number of atmospheres to which water resistance is ensured. 10 BAR means water resistance to 10 atmospheres. Watches marked “100m” have the same water resistance as 20 BAR watches

  • Full-Auto LED light

    A twist of the wrist in weak light conditions automatically lights up the display backlight.

  • Low-temperature resistant (-10 °C)

    Even temperatures as low as -10 °C have no effect on this watch.

  • Solar Power

    A solar cell provides power for operation.

  • Radio signal reception

    EU, USA, Japan & China
    Whether in Europe, North America and Japan or in the outer reaches of Canada, Central America and China - once the watch has been set to the local time, it receives the relevant signal and shows the correct time wherever you are. In many countries, it also sets itself automatically to summer and winter time.

  • Neo-display

    A luminous coating provides long-term illumination in the dark after only a short exposure to light.

  • Digital-compass

    A built-in direction sensor detecs the magnetic north.

  • Altimeter

    10,000 m
    A pressure sensor detects changes in the air pressure and converts the result into an altitude up to 10,000 m.

  • Barometer

    (260 / 1.100 hPa)
    A special sensor measures the air pressure (measuring range: 260 / 1100 hPa) and presents this on the display in the form of a symbol. This enables early detection of weather trends.

  • Thermometer

    (-10°C / +60°C)
    A sensor measures the ambient temperature around the watch and displays it in °C (-10°C /+60°C).

  • Height Gain

    The height gain sums all the meters you have climbed in a session, so that you can see at a glance the total ascent on a tour.

  • Altimeter data memory

    Depending on the model, up to 40 sets of elevation data can be stored in the watch's data memory and re-accessed at any time. Each of these data sets consists of a measured altitude as well as the date and time. In addition to the individual altitudes, the maximum and minimum altitudes during a measurement are also stored.

  • World time function

    Displays the current time in major cities and specific areas around the world.

  • Stopwatch function

    - 1/100 sec. - 24 hours
    Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours.

  • Timer

    - 1/1 min. - 1 hour
    For fans of precision: the countdown timers help you to remember specific or recurring events by giving off an audible signal at a preset time. The time can be set to the nearest minute and up to 1 hour in advance.

  • 5 daily alarms

    The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. This model has 5 independent alarms for flexible reminders of important appointments.

  • Automatic hand adjustment

    The automatic hand adjustment function checks the home position of the hands every hour and corrects it if necessary — either by adjusting e.g. from shocks or using the influence of magnetism.

  • Button tones on/off

    The button tones for using the mode button can be turned off. This means that the watch no longer beeps when switching from one function to another. Preset alarm or countdown timers remain active when the button tones are deactivated.

  • Hand Moving Function

    With a push of a button, hands are moving and permit a free visibility of functions like stopwatch or date.

  • Crown button lock

    Secures the crown button from accidental change to another mode of operation.

  • Smart Access Technology

    Smart Access makes it easy to operate multi-function watches. Simply pulling out and rotating the crown provides intuitive control over all functions

  • Calendar

    Automatic calendar with Date, Day and Month
    Once set, the automatic calendar always displays the correct date.

  • Resin case

    The resin housing is the ideal everyday companion. It is durable, lightweight and relatively insensitive to cold, heat or other external influences.

  • Full-Auto LED light
    A twist of the wrist in weak light conditions automatically lights up the display backlight.
  • Low-temperature resistant (-10 °C)
    Even temperatures as low as -10 °C have no effect on this watch.
