CASIO G-SHOCK SPORTS GBA-900-1A6DR G-SQUAD PURPLE BLACK WATCH

The GBA-900-1A6DR is the colour-pop standout in G-Shock's G-Squad fitness lineup — a black analog-digital case accented with translucent purple buttons and metallic teal index markers that give it a cyberpunk-inflected personality the all-black GBA-900-1A and red GBA-900-4A can't touch. It's a deliberately expressive colourway on a serious fitness platform: Bluetooth step tracking, GPS-corrected distance, auto lap, 45-run training memory, and a MIP digital display — all wrapped in a watch that looks like it belongs in a sneaker store as much as it does on a running track. The purple-and-teal combination works especially well against dark outfits, where the colour accents catch light without overwhelming the overall look.

The GBA-900 runs Casio's Module 5641, combining analog hands (with hand shift) and a MIP LCD for the digital readout — giving you an analog watch face for daily wear and a full-data fitness display for training. The step counter calculates daily steps, distance, and calories including basal metabolic rate, with a step goal progress gauge at 12 o'clock and a five-stage exercise intensity indicator always visible on the dial. GPS distance calibration through your phone lets the built-in accelerometer track pace and distance independently on familiar routes. At 61 grams with 200-metre water resistance and a soft urethane band, it handles the transition from morning run to office desk to evening gym without needing a strap change.

Why You'll Love It

• The purple-and-teal accent combination on a black base is one of the most distinctive colourways in the entire G-Squad range — it reads as stylish rather than sporty, which means you'll actually wear it outside the gym.
• Analog hands for daily timekeeping, MIP digital display for training data. You get the look of a proper watch with the functionality of a fitness tracker, without the compromises of either format alone.
• The step goal progress gauge at 12 o'clock and exercise intensity indicator are always visible on the analog face — no button presses or mode switching to check your daily activity.
• GPS distance calibration means accurate pace and distance tracking on familiar routes without carrying your phone. Calibrate once, run phoneless after that.
• At 61 grams with a soft urethane band, it's light enough for long runs and comfortable enough for all-day wear. The band doesn't trap sweat the way stiffer resin straps do.
• The translucent purple buttons and teal markers catch light at different angles, giving the watch a shifting, layered appearance that flat-colour G-Shocks don't have.

Key Features

• Bluetooth smartphone link with CASIO WATCHES app — Auto time sync, GPS distance calibration, training data review, life log management, and simple notifications (tone alert) all managed from your phone. The app also enables Strava sync for sharing runs.
• Built-in accelerometer with auto lap — Tracks distance, speed, pace, and calories once GPS-calibrated. Auto lap marks every set distance automatically, with 45-run memory storing lap/split data, total time, distance, average pace, and calories per run.
• MIP LCD digital display — The digital readout at 6 o'clock uses Memory-in-Pixel technology for superior sunlight readability. The analog hands handle everyday timekeeping while the MIP display shows training data, date, and function modes.
• Hand shift feature — Analog hands physically retract when you access digital functions, clearing the view of the display at 6 o'clock. They return to the correct time automatically when you exit.
• On-dial fitness indicators — Step goal progress at 12 o'clock (MIN/MAX gauge) and five-stage exercise intensity are always visible without switching modes. You can glance at your wrist mid-conversation and know exactly where you stand for the day.
• Double LED Super Illuminator — Separate LEDs light the analog face and the MIP digital display independently, with auto light, selectable duration (1.5s or 3s), and afterglow. Both fire white for consistent nighttime readability.
