Watch Sizes Guide
Understanding watch sizes is essential for finding the perfect fit. Here's everything you need to know.
Key Measurements
- Case Diameter — Width of the watch face (most common measurement)
- Lug-to-Lug — Total vertical length including lugs
- Case Thickness — How tall the watch sits on your wrist
- Lug Width — Determines strap compatibility
Size Recommendations by Wrist
| Wrist Circumference | Recommended Size |
|---|---|
| Under 6" (15cm) | 34-38mm |
| 6" - 7" (15-18cm) | 38-42mm |
| 7" - 7.5" (18-19cm) | 40-44mm |
| Over 7.5" (19cm+) | 42-46mm+ |
The Golden Rule
The watch lugs should never extend past the edges of your wrist. If they overhang, the watch is too big.
