Fit tips
· Measure ring size at the end of the day when fingers are warmest.
· If between sizes, choose the larger size for comfort bands.
· EU sizes below are circumference (mm) — the usual NL/EU jeweler scale.
· Watch case size is diameter across the face, not strap length.
· Engraving does not change fit — size for wear first, mark second.
· Blank (unengraved) rings: contact Support within 14 days for size exchange if unworn.
Available on this blank: 54, 56, 58, 60, 62
