The third material has
the lightness of resin and
a strength exceeding that of metal.


Beginning from the newly developed carbon monocoque case, the watch makes use of 
high-performance carbon materials that exhibit strength and lightness in countless locations. 
The design achieves the shock resistance required of a pilot’s watch, while at the same time weighing just 72 g, 
the lightest watch in the GRAVITYMASTER lineup.

This new shock resistant structure protects modules with a carbon fiber reinforced resin case.

Bezel with 52 layers of carbon sheeting

The bezel is made of carbon materials as well, making it highly durable and resistant to damage. The layered carbon bezel is designed to keep flexibility and to absorb shock. It is achieved by making a clearance between the case and the bezel.

Carbon monocoque case

The case and back cover are part of a unified construction that ensures that the watch is both strong and airtight. In addition, the use of carbon materials grants greater freedom of design while increasing shock resistance.

Shock resistant button

A cleaner design that removes the button guard was achieved through improved case strength and the newly developed structure.

Technology /



Titanium materials are used for the metal parts that are exposed to outside air, making them lightweight, strong, and resistant to rust.



Shock, centrifugal force, and vibration-resistant structure.

Further improvements in the shadow dispersing solar panel by optimizing solar cell shapes to improve power generation efficiency and make it possible to generate sufficient power using only the light received through the dial areas of the face. This eliminates the need to limit the transmittance of the face, which greatly enhances face design possibilities.

Stopwatch with flyback function

Stopwatch with with flyback function

The button at 2 o'clock can be used to start a stopwatch operation while in the stopwatch mode. During a stopwatch operation, a single press of the button at 4 o’clock instantly stops the current operation, resets the stopwatch, and starts a new lap time. This flyback feature avoids time lost to button operations.

Bluetooth® 搭載電波ソーラー

Bluetooth® Radio-controlled,  solar-powered  timekeeping

Time correction is conducted by either Bluetooth® communications or standard time radio wave (Multi Band 6), depending on the circumstances. Reception of the most recent time zone and Daylight Saving Time information assures that the correct time is displayed at all times.
