Not sure which case size to pick? Measure your wrist, check it against the table below, then compare it with the approximate sizes of each Rosevari shape. Every case size follows the reference design it is modelled on, so the figures here are approximate.
How to measure your wrist
- Wrap a soft tape measure (or a strip of paper) around your wrist just above the wrist bone, where a watch normally sits.
- Keep it snug but not tight. If you used paper, mark where it overlaps and measure the length with a ruler.
- Note the figure in millimetres or inches and find it in the table below.
Recommended case size by wrist
| Sizes | Wrist circumference (mm) | Wrist circumference (in) | Recommended case diameter |
| XS | < 150 | < 5.9 | 36 mm |
| S | 150 - 165 | 5.9 - 6.4 | 36 mm |
| M | 165 - 180 | 6.4 - 7.0 | 36 - 40 mm |
| L | > 180 | > 7.0 | 40 mm |

A few rules of thumb
- Smaller wrists, or a dressier look: 36mm and under wears neatly under a cuff.
- Average wrists: 36mm to 40mm covers most people. Pick the lower end for a classic fit and the upper end for more presence.
- Larger wrists: 40mm and up keeps the watch in proportion.
Fitting the bracelet
Every Rosevari watch comes with a presentation box and a sizing tool, so you can take bracelet links out yourself at home. Remove links evenly from both sides of the clasp so the watch sits centred on your wrist. The Owner's Manual covers bracelet sizing step by step.
