Case Diameter.
CASE DIAMETER | WRIST SIZE |
---|---|
34mm to 36mm | <6 inches (15cm) |

Wrist Sizes

To measure a watch case size, place calipers from one side to the opposite side of the case, just above or below the crown, where the case diameter is the smallest. The easiest way is to measure the case from the 4 o'clock to 10 o'clock position or from the 2 o'clock to 8 o'clock position.
To find your perfect size within the range, use your wrist measurement. If your wrist is between 14cm – 18cm, select a small or medium watch with a diameter of 38mm, 40mm, or 42mm. If your wrist is 18cm and above, choose a larger case, such as one that is 44-46mm.
What size is a 7 inch wrist?
Watch Size For A 7in Wrist
6 inch wrist – Small to medium diameter cases around 34-38mm. 7 to 7.5 inch wrist – Considered average mens wrist size. 38-42mm range will fit best. 8 inch and larger – Considered a large wrist size.
If you have a wrist between 6.5″ – 7.5″, you're in luck, as the majority of modern watches will fit your wrist. Consider watches between 36mm – 42mm in diameter. If you have wrists 7.5″ – 8″ or larger, consider watches that are 39mm or larger, as they will likely fill your wrist most appropriately.

Knowing your wrist size
Read the measurement as it appears through the slit. Generally, 5.5-6.5 inches is considered a small wrist, 6.5-7 inches a medium wrist and 7+ inches a large wrist.
For men, a small wrist size is anything under 6.5 inches, whereas a small wrist measurement for women is anything under 5.5 inches.
Finally, your oversized watch should not slide up or down your wrist more than an inch when you drop your arms to the side. An oversized watch that also slips up and down your arm looks sloppy.
If you're unsure, it's best to go for a watch of around 36mm diameter which is a standard mid-size. More rounded or larger wrists can get away with any of the Rolex sizes which go right up to a 44mm. Always remember that the larger the watch you choose, the harder it is to wear the watch discreetly.
