My GShock

ADD TO BAG

A GPS hybrid radio-controlled, solar-powered model from G-SHOCK's most luxurious line, MR-G. The first watch to be equipped with a shock-resistant structure and GPS hybrid radio solar in a full metal case, it can display accurate time all over the world. Additionally, the clad guard structure makes the crown both operable and impact-resistant, which was previously difficult. The titanium case and band have undergone DLC and deep hardening treatments and are finished in all black to achieve a tight design. Particular attention was also paid to every detail affecting strength and quality, as is reflected in the use of textured polishing, and an anti-reflective coating on the sapphire glass crystal. It is a model that imbues tough men around the world with the pride of MADE IN JAPAN.

Technology

The ultimate in precision and strength

GPS Hybrid Wave Ceptor*1

A system that can receive both GPS satellite and terrestrial radio waves
to display the correct time anywhere in the world, whether indoors or outdoors.

MRG-G1000B-1A | G-SHOCK MR-G Black | CASIO (18)

GPS satellite radio reception

  • Acquires current location and time information from GPS satellites
  • Determines current location through approximately 500m high-resolution map data
  • Automatically analyzes time zone and Daylight Saving Time information to display the correct time, with automatic time reception once a day*2
MRG-G1000B-1A | G-SHOCK MR-G Black | CASIO (19)

Terrestrial radio wave reception (Multi Band 6)

  • Receives terrestrial radio waves from six transmission stations worldwide
  • Supports radio wave reception both indoors*3 and outdoors
  • Automatic night-time radio wave reception (up to 6 times) minimizes the possibility of reception failures in order to maintain accurate time display
  • Receives data with minimal power consumption

*1 A mechanism powered by Casio's proprietary solar-charging system that uses GPS (Global Positioning System) to measure positioning and corrects time through radio waves.
*2 When outside the terrestrial radio wave area.
*3 In environments where radio waves can be easily received, such as near a window.

Propelled by groundbreaking exterior design.

Clad guard structure

The crown, buttons, and guard parts are integrated for improved shock resistance and a more compact case, while innovative exterior design solves the issue of increased bulk associated with a built-in GPS satellite radio reception antenna. αGEL® is also used in the crown head cover to absorb shocks to the body of the crown.

Wear strength and lightness.

Titanium case and solid titanium band

The durable, lightweight titanium construction feels light on the wrist despite being fully metal. As titanium is hypoallergenic, even those allergic to other metals can wear it without worry.

MRG-G1000B-1A | G-SHOCK MR-G Black | CASIO (22)

Retains the rugged shine of titanium.

Double hardening treatment

Deep hardening treatment*2 provides 4 to 5 times the hardness of pure titanium. The surface also has a diamond-like carbon (DLC) coating.

Bright, illuminated dial.

Super Illuminator

Equipped with a high-brightness white LED. Ensures visibility in dark conditions, such as night-time and bad weather.

MRG-G1000B-1A | G-SHOCK MR-G Black | CASIO (24)

Simultaneous time display for two different cities.

Dual time zone display

Simultaneous timekeeping for two different cities on the main dial and sub-dial. World time can be set by a simple twist of the crown.

Scratch-resistant for a brilliantly transparent, clear view.

Sapphire glass with non-reflective coating

The crystal is made using highly transparent, scratch-resistant sapphire, with a non-reflective coating on the inner surface for clear visibility.

MRG-G1000B-1A | G-SHOCK MR-G Black | CASIO (29)

Looks and feels good on your arm.

Separate band

The strengthened H piece gives the two-piece structure an edgier finish. Adhesion of each part is improved and rotation of the piece is suppressed, preventing scratches against other pieces and reducing rattling when worn.

MRG-G1000B-1A | G-SHOCK MR-G Black | CASIO (30)

Prevents the band from coming loose while worn.

Clasp with tight locking mechanism

The one-push tri-fold clasp is equipped with a locking mechanism that prevents the band from coming loose while worn. The highly reliable buckle is unique to the MR-G.
