Before you decide

What to verify for this g-shock

These checks are tailored to the product department and help separate permanent model specifications from details that can vary by seller or market.

  1. 01

    Confirm the exact Casio GA-100-1A2 variant, included accessories and local warranty terms before purchase.

  2. 02

    Use the displayed price as a dated reference only; current price and stock can differ by retailer, city and configuration.

  3. 03

    Confirm the exact case, dial and band code because visually similar watch variants can use different materials and finishes.

  4. 04

    Check water resistance, battery or solar system, dimensions and local service support against your intended use.
