watchatlasStop shopping by case diameter.
Two 40 mm watches can wear completely differently. The number that decides fit is lug to lug: the distance from the tip of the top lugs to the tip of the bottom lugs.
Measure the flat top of your wrist. If the lug to lug is shorter than that, the watch will usually sit well.
What's your flat wrist width, and what's the best-fitting watch you own? Tell us below.
Save this for your next watch hunt.
