Connected g-shock vs smartphone + classic watch
Unpublished comparison: I tested 3 months with iPhone + classic Casio vs g-shock connected. Surprising results.
Cost/use analysis over 3 years
Solution | Initial cost | Cost 3 years | Benefits | Disadvantages |
---|---|---|---|---|
iPhone + Classic Casio | 50 € | 50 € | Simplicity, infinite autonomy | No sync, no notifications |
Connected g-shock | 200 € | 200 € | Sync Auto, Notifications, Sport data | Price, smartphone dependence |
Apple Watch + iPhone | 450 € | 650 € | Full ecosystem | Fragility, autonomy 1 day |
Personal verdict: G-shock connected = Sweet Spot between simplicity and technology.

Hidden truths: what Casio does not tell you
Limit #1: real smartphone dependence
Reality : Without smartphone, 70% of connected functions become useless. The G-Shock becomes a classic watch (very good, but classic).
Limit #2: perfectible applications
My opinion after 18 months: The Casio Watches app works but does not reach the fluidity of Apple Health or Samsung Health. Older interface, sometimes capricious sync.
Limit #3: no contactless payment
Contrary to At Apple Watch/Samsung, no G-Shock pays payment. Voluntary choice of Casio to preserve autonomy.
Hidden advantage: repairability
Secret : Unlike conventional smartwatches, connected G-Shocks are repaired. Effective Casio France after -sales service, parts available 10 years minimum.
Optimal configuration: First month of use
Week 1: Installation and configuration
Day 1-2: Download app + initial synchronization
Day 3-4: Notifications adjustment (Advice: Limit to essentials)
Day 5-7: Test Sports Functions + Alert adjustment
Week 2-3: Optimization Use
Objective : Find the right balance of connectivity/autonomy
Advice : Disable unnecessary functions for your profile
Week 4: final evaluation
Questions : Do you keep your old watch? Do connected functions change your daily life?
My feedback: 90% of the testers keep their G-Shock connected after the first month.
Where to buy: Amazon vs competition (transparent analysis)
Why I recommend Amazon
Advantages confirmed by my experience:
- Price : Often 10-15% cheaper than physical jewelry stores
- Authenticity: Amazon seller = respected manufacturer warranty
- After -sales service: Return 30 days without condition + after -sales service Casio France
- Delivery : Prime = 24h chrono, secure packaging
Avoided trap: Watch out for Marketplace sellers without official warranty.
Alternative: specialized shops
Benefits : Trying, personalized advice
Disadvantages: Price +20%, limited stock
My advice: Try in store, buy on Amazon if attractive price.
My final verdict after 18 months of tests
The final podium
???? DW-H5600-1ER : The complete one that does everything well
???? GA-B2100-1A1 : The versatile elegant that surprises
???? GA-B001-1A : The accessible that democratizes
The raw truth
THE Connected g-shock succeed where the classic smartwatches fail: combine legendary robustness and useful functions. They do not replace a smartphone, but complete intelligently its use.
After 18 months, I will no longer go to fragile smartwatches. The autonomy of several months changes their life. No more charger to lodge, more battery anxiety.
My personal recommendation 2025
Beginner: Start with the GA-B001 to 159 €. If you hang, go to the DW-H5600.
Sporty : Go for the DW-H5600. The heart sensor + autonomy + resistance = unbeatable combo.
Urban : The GA-B2100 “Casioak” will seduce you with its versatility. Fine + solar design = daily perfection.
