Why Watch Sizing Matters
A beautiful watch on the wrong wrist can look completely out of place. Too large and it looks costume-like; too small and it disappears. Getting the sizing right is one of the most important — and most overlooked — aspects of buying a watch. The good news is that with a few simple measurements, you can find the ideal size with confidence.
Step 1: Measure Your Wrist
Use a flexible tape measure or a strip of paper to measure the circumference of your wrist, just above the wrist bone where you'd normally wear a watch. Note the measurement in millimetres.
- Small wrist: Under 160mm
- Medium wrist: 160–180mm
- Large wrist: Over 180mm
Step 2: Match Your Wrist to a Case Diameter
Case diameter is the most commonly cited sizing measurement. Here are general guidelines:
- Under 160mm wrist: 34–38mm case diameter works best
- 160–170mm wrist: 38–40mm is the sweet spot
- 170–180mm wrist: 40–42mm suits well
- Over 180mm wrist: 42–44mm+ can be worn comfortably
These are guidelines, not rules. Personal style and preference play a role — some people prefer an oversized look, others a more discreet fit.
Step 3: Consider Case Thickness
A thinner case (under 10mm) will sit closer to the wrist and feel more elegant. A thicker case (12mm+) has more presence but can feel bulky under shirt cuffs. If you frequently wear tailored suits or formal attire, prioritise a slim profile.
Step 4: Check the Lug-to-Lug Distance
The lug-to-lug distance — the measurement from the tip of one lug to the tip of the opposite lug — is arguably more important than case diameter for fit. A watch with a short lug-to-lug will sit neatly within your wrist; a long lug-to-lug will overhang the edges, which many people find uncomfortable.
As a rule of thumb, the lug-to-lug distance should not exceed your wrist width. Measure the width of your wrist (side to side, not circumference) and compare it to the watch's lug-to-lug spec.
Step 5: Get the Bracelet or Strap Length Right
Most watches come with straps or bracelets that can be adjusted. Steel bracelets typically have removable links — a watchmaker or jeweller can remove links for a perfect fit. Leather and rubber straps usually offer enough adjustment through their buckle holes, but check the strap length if ordering online.
The ideal fit: you should be able to slide one finger comfortably under the strap, and the watch should not slide more than a centimetre up or down your wrist.
