Development Story

Until now, voice wristwatches have been developed and marketed on the premise that they are products for use by the visually impaired. Therefore, the focus has been only on functionality and not on fashion. In response to the market's need for a voice wristwatch that is also fashionable, we at INTEC have developed the GRUS voice radio-controlled wristwatches, a conventional product of ours. In the process of dealing with the GRUS voice radio-controlled wristwatches, we have received many comments from visually impaired people and para-sleuths overseas, such as 'I want a voice wristwatch that can be used overseas,' and 'I think it would be good if there were more luxurious voice wristwatches as well. 'I would like to have a voice watch that can be used overseas. We have received comments such as I want an audio wristwatch that can be used overseas. In response to these comments, we set out to create a high-performance, high-end voice wristwatch that could be used overseas. After three years of development, including specification, design, and fine-tuning of accuracy, the product was finally born in April 2023. In addition to functional enhancements such as automatic time correction by GNSS, six-language switching, and a brightness sensor, this voice-activated wristwatch features an advanced design with a simple, highly legible dial reminiscent of a pilot's watch.

Basic Functions

Introducing the basic functions of the GRUS GNSS Voice Watch

Time Notification By Voice

For example, in the 12-hour system, the time announcement is "3:58. On the other hand, for a 24-hour system, the time announcement would be "3:58 p.m.".

Calendar Notification By Voice

An example would be the announcement "October 12, Thursday". The calendar information is also corrected when the GNSS signal is received, so it will not be out of alignment.

Features Only For GNSS Voice Wristwatch

Unique features you won't find anywhere else

GRUS GNSS Voice Watch maintains simplicity of operation while pursuing a high level of functionality. Here are some of the unique features of GRUS that are not found in other voice-activated watches.

  • Automatic Time Adjustment by receving GNSS Signals

    The watch automatically receives GNSS signals and automatically adjusts the time and date. One of the major problems with conventional voice wristwatches is that it is difficult for the visually impaired to adjust the time if the time is off. The GNSS Voice Watch can always indicate the exact time with this function. GNSS is a generic name for a set of satellites orbiting above the Earth. In Japan, the Quasi-Zenith Satellite MICHIBIKI is one such satellite.

  • Brightness sensor

    The light is detected by a light collecting window installed on the dial of the wristwatch, allowing the user to know the brightness of the surrounding environment. It can be used as an indication of whether it is sunny or cloudy outdoors, and whether the lights are on or off indoors.
