Casio adds a heart rate monitor and Smartphone Link to the G-LIDE series, targeting surfers who already use its tide graph.
Key Takeaways
The G-LIDE is a surf-oriented G-SHOCK line known for tide graphs; HRM and Smartphone Link are new additions to this specific sub-series.
Smartphone Link enables automatic time correction and notification sync when paired.
Power is split: USB charging drives HRM, step tracking, and notifications; solar charging sustains the time display when the main battery is depleted.
Battery life is approximately 35 days with connected features active.
Hacker News Comment Review
The “first G-SHOCK with HRM” headline is factually wrong according to commenters: Wear OS G-Shocks and G-Move models already had HRM; this is only the first in the G-LIDE series.
Several commenters flagged the Smartphone Link pairing requirement for automatic time correction as a downgrade, since many existing G-Shocks already sync via radio signal without a phone.
The battery split design (USB for smart features, solar for timekeeping fallback) drew interest as a practical hybrid model, but the 35-day limit compared to sub-month Garmin or Withings alternatives was seen as marginal for a “dumb smart watch” use case.
Notable Comments
@jerlam: Clarifies the “first G-SHOCK with HRM” claim is only true within the G-LIDE series; Wear OS G-Shocks and G-Move already shipped with HRM.
@zecg: Points out Casio’s radio-based auto time correction already exists and works without a phone, calling the Smartphone Link pitch “the best reason we found for mandating smartphone pairing.”
