Regular user in catering (frequent shocks) for 8 months, looking for a robust watch with basic activity tracking without frequent recharge. Choice motivated by the anti-shock reputation of G-Shock and the autonomy announced (2 years).

See the G-Shock GBA-800-1aer and the opinions on Amazon

First contact and installation

• Perceived quality: solid case, flexible resin bracelet (immediate comfort), 200 m waterproofing verified.

• Handing: intuitive interface (physical buttons), but inverted digital screen that is not very readable in broad daylight without backlight.

• Bluetooth connection: synchronization with the G-Shock app (iOS/Android) in 5 min, but minimalist design of the app (no detailed dashboard).

Real test vs promises

• Activities: reliable steps (gap ≤5 Pas vs fitbit), memory of 120 laps in stopwatch.

• Sustainability: resistant to shocks against walls/counters (no scratch after 8 months).

• Battery: 20 months of actual autonomy (Bluetooth activated 1x/day), far from the 2 years promised.

• Disittions: absence of GPS, illegible digital screen without backlight, too simplistic app.

Key points for the buyer

• For whom: manual workers, occasional sportsmen, G-Shock fans looking for a basic hybrid.

• For whom not: runners (no GPS), Tech-Addicts (limited app), small wrists (massive model).

• Corporate value for money: correct at 150 € for robustness, but alternatives (Xiaomi Miband, Garmin Instinct) offer more features at the same price.

Cash verdict✅ 3 strengths:

1. Indestructible (shocks, water, dust).

2. Unbeatable autonomy vs smartwatches.

3. Prolonged comfort despite the size.

❌ 3 weak points:

1. Digital display unusable in broad daylight.

2. Rudimentary app (no in -depth analysis).

3. Actual battery lower than promises.

Recommended ? Yes, for hostile environmental workers or fans of lasting low-tech watches. Not recommended for demanding athletes or precise data followers.

Why was this product designed? (Creation context, origin)The G-Shock GBA-800-1aer meets a double requirement: integrate connected technologies in a sports watch while retaining DNA anti-shock brand history. Designed in 2018 for the G-Squad range, it targets the urban sports and the followers of athleist (mix between sporting and daily outfit).

Technical origin

• G-Shock heritage : Hollow structure of the case inspired by the first models (1983), with suspended module to absorb shocks. Omnidirectional coating protecting pimples and glass.

• Innovation 2018 : Integration of a 3 -axis accelerometer For activity monitoring + bluetooth low energy to synchronize with the Casio app.

Market objectives

1. Retain G-Shock purists With a hybridizing robustness version (resin, 200m seal) and basic smart functions.

2. Compete with the wearables (Fitbit, Xiaomi) via an activity tracker Without frequent recharge (autonomy 2 years).

3. Capture occasional athletes via training tools:

   • Combinable timer (20 5 timers combinations)

   • Memory of 200 laps in Stopwatch mode

   • Monitoring of calories and daily objectives

Strategic choice

• Digital backlit digital screen rather than a touch screen (risk of fragility).

• Minimalist To avoid functional overload, aligned with the low-tech G-Shock spirit.

• Design unisex (48.6 mm box) and sober color to adapt to all styles.

This watch embodies a Controlled transition Towards connected, without compromise on sustainability - the brand's historic keystone.
