     Description (6,374 characters)
Set contents: Main unit, box, instruction manual, warranty card included in the instruction manual
Enhanced waterproof for daily life: 20 BAR
Country of Origin: Japan
Radio solar for 6 stations worldwide (Japan x 2, North America, UK, Germany, China)
Shock-resistant structure that is resistant to shock and vibration
Triple sensor capable of measuring direction, altitude/barometric pressure, and temperature
Double LED light that illuminates the dial and liquid crystal (with a full auto light function that lights up when the arm is tilted only when the brightness is judged and judged to be dark (only when the full auto light is ON))
Product introduction Brand description: G-SHOCK, which has built a new concept of toughness in watches.
It all started with the developer's passionate belief in creating a watch that would not break even if dropped, and a reckless challenge that overturned the common sense of the time.
Over 200 prototypes were repeated, and it took about two years to complete, and the impact-resistant structure was completed.
It is the birth of technology that plays a core role in toughness.
Since then, G-SHOCK has continued to evolve endlessly.

Model Master of G "Gulfmaster" for use on the sea, one of the harshest natural environments on earth.
Equipped with G-SHOCK's first "triple sensor Ver. enabled
We have evolved the barometric pressure measurement function, which is the information most needed by the crew.
Equipped with an in-dial pointer and digital display, and an atmospheric pressure trend information function that alerts you with an alarm when there is a sudden change in atmospheric pressure due to an approaching storm or low pressure.
It also has a function that allows you to quickly check changes in atmospheric pressure by pointing the carbon fiber second hand to the numerical value engraved on the bezel. rice field
Equipped with azimuth measurement, tide graph/moon age display, which are essential functions when performing missions at sea, and temperature measurement function, which is important information in unforeseen situations.
The design is inspired by the instruments and compasses of a ship, giving the impression of the sea.
The bezel, buttons, and screws all have a uniform circular shape, and the watch has a form that makes it difficult for the watch to interfere with ropes and equipment on board.
In addition, the light button and sensor button, which have important functions, use aluminum ring composite buttons colored in blue and red to support sensible operation.
The large crown has a quick lock mechanism that maintains waterproof performance, realizing operability and toughness design.
In order to challenge the limit of the sea, it is the appearance of Gulfmaster, which has further evolved functions.
