New G-SHOCK GRAVITYMASTER in Collaboration with HondaJet

Casio Computer Co., Ltd., has released a new addition to the G-SHOCK GRAVITYMASTER series of aviation concept watches, the GWR-B1000HJ. The design of GWR-B1000HJ is inspired by the design of the advanced light business jet HondaJet Elite. It is the world’s most-delivered* light business jet in its class, manufactured by Honda Aircraft Company, a subsidiary of American Honda Motor Co., Inc.

* According to a survey by the General Aviation Manufacturers Association (GAMA)

With an innovative Over-The-Wing Engine Mount configuration, HondaJet has redefined conventional aircraft design. HondaJet is a fitting collaboration partner for G-SHOCK, as the two brands share the same commitment to always taking on new challenges and leveraging the most advanced technology.

The new GWR-B1000HJ is based on a design sketch by Michimasa Fujino, who is responsible for the design and development of the HondaJet. The watch features an aircraft-shaped indicator for the inset dial just below the 12 o'clock position. The curved-knurl finish on the watch crown was inspired by the shape of the HondaJet engine fan blade, while the button pipes at the 2 and 4 o'clock positions are mirror finished, just like the jet's engine cowling. The HondaJet logo can be found on the watch dial, crown, and bands. The upper watch band also conveys the aircraft’s best- in-class flight performance in details.

Casio watch designers visited the United States to see Honda’s latest aircraft, the HondaJet Elite. Inspired by this visit, they faithfully captured the jet’s white base and metallic finish and applied these colors to parts such as the watch dial and logos. The design reflects many aspects of the HondaJet worldview.

This GWR-B1000HJ is based on the GWR-B1000 model, features an innovative shock-resistant Carbon Core Guard structure that makes the most shock resistance, stiffness, and durability of carbon fiber, and this material also employed in aircraft fuselages. This special collaborative model resonates with the pursuit of toughness and the world of aviation.
