Will it fit your wrist?
At 31 mm, this watch fits a 14-17 cm (5.5-6.5 in) wrist. Most Rolex bracelets adjust to your size by adding or removing links, so the fit is not a fixed length.
Tell us your wrist size when you order (add it in the order notes) and we pre-size the bracelet before it ships — it fits the day it arrives, no jeweler.
