Take your daily training to the next level in both style and comfort with a G-SHOCK specially engineered for urban sports.

Find more joy in your workout with the GBA-950, which comes packed with practical features to support your training regime. Use your smartphone’s GPS functionality to adjust distance measurements, after which the watch can track your pace even without a smartphone connection. Use the Auto Lap feature to automatically keep track of times over a set distance, and tap into the dedicated app to easily manage life log data, review activity history, and more.

The bezel and band are seamlessly molded into a single exterior piece, providing robust protection for the carbon fiber-reinforced resin case. The band construction, designed for maximum flex, delivers an even more comfortable fit on the wrist. Additionally, the adhesive glass attachment allows for a more compact lug design, enhancing the sharp silhouette from the bezel to the band.

The new band design was developed in collaboration with OUTSENSE Inc., a leader in the field of “origami engineering.” Their insights, gleaned from the art of paper-folding, deliver a band with depth and dimension, and an exceptionally comfortable fit. Precisely analyzed mountain and valley fold angles in the band’s base sections pull outward to the left and right, ensuring the case fits snugly against the wrist on the underside of the band’s wave-shaped base.

Key resin components used in the bezel and band are also made of bio-based resin, a material expected to help reduce environmental impact.

Sync with your smartphone via Bluetooth® for precision timekeeping, simple notification (sound alert), step counts, and more. Offering a 2-year battery, this watch is ready to help you with everything from managing daily health to boosting your running endurance — all with a fashionable sporty look.
