How to measure
Ring fit
Wrap a paper strip around the finger, mark the overlap, measure in mm — that's circumference (EU). Match US or EU below.
Inner Ø
- US 6 · EU 51–52Ø 16.5 mm · 51.9 mm
- US 7 · EU 54–55Ø 17.3 mm · 54.4 mm
- US 8 · EU 57Ø 18.1 mm · 57 mm
- US 9 · EU 59–60Ø 18.9 mm · 59.5 mm
- US 10 · EU 62–63Ø 19.8 mm · 62.1 mm
- US 11 · EU 65Ø 20.6 mm · 64.6 mm

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: 6, 7, 8, 9, 10, 11, 12
