Sources and measurement notes

Sizometry compares published specifications and calculates differences. These are not hands-on measurements or tests of comfort, performance or pocket fit.

Check the exact model, year, region and configuration on the linked page. References may cover several variants. Folded and unfolded dimensions differ; cases and camera protrusions may change the space a device needs. Drawings share a relative scale and are not calibrated to life size on your screen.

Sizometry Analysis

Everyday usability

Estimated from the watch’s size, weight, battery, display, and intended wearing conditions.

  • Wrist comfort

    Noticeable

    The larger case gives it a noticeable wrist presence, especially on smaller wrists.

  • Sleep comfort

    Noticeable

    Users sensitive to wrist pressure may prefer a smaller and lighter model overnight.

  • Battery usability

    Data unavailable

    Available battery information is insufficient for a reliable daily-use assessment.

  • Screen and controls

    Good

    Detailed brightness information is unavailable, so outdoor visibility cannot be fully assessed.

  • Workout usability

    Excellent

    Its low weight, water resistance, and GPS support make it well suited to running and gym sessions.
