Seiko Watch Specifications: Compare Sizes & Check Wrist Fit

Seiko Watch Size Guide

How to Choose the Right Seiko Watch Size

1. Measure your wrist — Wrap a measuring tape around your wrist just below the wrist bone. Note the circumference in millimeters. See our measurement guide.
2. Check lug-to-lug — Compare the watch's lug-to-lug distance against your wrist width using our interactive watch fit tool. It should be equal to or slightly less than your wrist width for the best fit.
3. Consider thickness — Thicker watches sit higher on the wrist and may catch on sleeves. If you wear dress shirts, look for models under 12mm.
4. Use our comparison tool — Add any Seiko watch to the interactive size comparison to see it overlaid on your wrist size.
