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

    Substantial on the wrist

    Despite its large footprint, the relatively low weight keeps it manageable for daily wear.

  • Sleep comfort

    Bulky

    The large, heavier case is more likely to feel bulky overnight.

  • Battery usability

    Data unavailable

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

  • Screen and controls

    Excellent

    The large, bright display is easy to read at a glance, with touch input for everyday controls.

  • Workout usability

    Well suited

    Strong water resistance and GPS availability improve its usefulness for outdoor training.
