From around six millimetres, where the dome is present but restrained and the band is a firm, deep bracelet, through eight, ten and twelve millimetres, in which the profile is unmistakable on the wrist.
Fourteen, sixteen and eighteen millimetres are made for those who want the wrist to carry a broad domed band, and wider is produced. At these widths the clasp carries a latch on each flank.
The form of the link is constant; what grows with the width is the depth of the dome and the mass of each segment. Each listing gives the width and karat of that bracelet.
