From This new model is the first in the GRAVITYMASTER lineup to be equipped with digital compass capabilities, creating a watch that is 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 mode you were in before the Digital Compass 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. Bearing Memory lets you temporarily store and display a direction reading so you can use it as a reference as you take subsequent digital compass readings. Other 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 for easy reading in the dark.

A new type of resin bracelet type band uses "Fine Resin"* square elements combined with steel-embedded H-shape elements, which enables both lighter weight than metal without sacrificing durability. The bracelet configuration also provides a better fit than standard resin bands.

* Fine Resin

Fine Resin is a type of polyamide resin that is strong and highly resistant to chemicals as well as discoloration caused by UV light. It has been approved as a Class VI product by the U.S. Pharmacopeial Convention (USP). These properties combined with the fact that it is light weight makes it perfect for aviation applications.
