Fiery and bold G-SHOCK watches glowing with flames of awesome color.
G-SHOCK is all about taking on challenges, and the vivid colorful gradation of the Flame Inside line puts this blazing passion front and center.
Beginning with the GA-100 with distinctive large case and the GA-2100 with octagonal case, the design brings in motifs of billowing smoke for the band and features a brightly burning dial in flames of blues or oranges.
Choose your favorite look — the GA-100FL-1A or GA-2100FL-1A with vivid blue dial and gradated gray-on-black body, representing the hottest flames of conviction against rising white plumes of smoke; or the GA-100FL-8A or GA-2100FL-8A with bold orange dial and gradated black-on-gray body, evoking flames of fiery passion against a dark smokey backdrop.
