G-Shock Digital & Analogue Watch Gravitymaster Series GA1000-4B / GA-1000-4B

This new model is the first in the Gravity Defier lineup to be equipped with digital compass capabilities, creating a watch perfectly matched to the needs of the modern aviator both in terms of function and appearance. Pressing the 9 o'clock button in any mode immediately goes to the Digital Compass Mode, and a button at 8 o'clock returns to the previous mode. Continual direction readings can be taken for 20 seconds, during which the second hand points to north; a literal direction indicator is displayed in the upper display, and a direction angle value is displayed in the lower display. For those interested in similar functionality, consider exploring models like the G-Shock GA1000-4A and G-Shock GA1000-1A, which also provide the rugged features G-Shock is known for. 

The Gravitymaster GRB300 Series, including options like the GRB300-8A2 and GRB300-1A4, also features advanced navigation tools and shock-resistant technology. For convenient navigation, Bearing Memory lets you temporarily store and display a direction reading so you can use it as a reference when taking subsequent digital compass readings. Additional features include temperature measurement, large numerals, and thick hands for easy reading. A coating on the tip of the second hand and minute markers reacts with the black light illumination of the watch, ensuring easy readability in dark conditions.
