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

    Comfortable

    The case size and body-only weight should feel comfortable for everyday wrist wear.

  • Sleep comfort

    Comfortable

    Its size and weight should remain comfortable for most users overnight.

  • Battery usability

    Data unavailable

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

  • Screen and controls

    Easy to use

    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.
