Casio announced Kanoa Igarashi 2nd Signature G-SHOCK - TGH Technology and Business Portal/Blog

Casio recently announced the latest addition to the G-LIDE line-up of watches for extreme sports – Kanoa Igarashi 2nd Signature G-SHOCK watch. The G-LIDE line of watches for extreme sports are part of the G-SHOCK brand of shock-resistant watches. This new GBX-100KI is the second signature model endorsed by pro-surfer Kanoa Igarashi. For Casio and G-SHOCK fans, as well as those into extreme sports, this new G-SHOCK GBX-100KI would definitely interest you!

Igarashi started surfing at the age of three. Since then, he has gone on to win several major surfing competitions and is currently a world-class professional surfer competing on the World Surf League (WSL) Championship Tour at the top of the sport.

The base model of the second Kanoa Igarashi signature model is GBX-100, equipped with Mobile Link functions in addition to a useful tide graph for surfers. The new GBX-100KI is a special-edition watch with a design and color theme created under his supervision. The all-black timepiece is adorned with different textures and shades for each part including the bezel, band, and LCD, expressing his cool and unique worldview. The bezel and glass feature a graphic of Igarashi himself tube riding a massive wave. The dial, case back, and band tip feature his signature. The lug side of the band showcases the number 50, which is his number on the WSL Championship Tour.

The GBX-100KI is also equipped with Mobile Link functions that pair with a smartphone. With the dedicated smartphone app, the user can select a location from approximately 3,300 preset locations worldwide and send the information to the watch, including tide data, sunset/sunrise times, and other essential data for surfers. In addition to displaying tide graphs and moon data, the watch comes with several functions which are advantageous in daily training, such as distance traveled, time, and pace. The wide watch face uses a high contrast Memory in Pixel (MIP) LCD for optimum visibility.
