The short answer: measure your wrist with a tape or a piece of string. Up to 16 cm a 36–38 mm case suits you best, 16–18 cm takes 38–40 mm, and above 18 cm 40–41 mm. Every watch we make is between 36 and 41 mm, so yours is somewhere on this scale.
How to measure your wrist
- Take a tailor's tape. If you haven't got one, use string or a strip of paper and measure it against a ruler afterwards.
- Wrap it around your wrist where you normally wear a watch — just behind the wrist bone, towards the elbow.
- Pull it so it touches the skin without squeezing. A finger should fit between the tape and your wrist.
- Read off the circumference in centimetres. That is your measurement.
Which case size to choose
| Wrist circumference | Recommended case | Our models |
|---|---|---|
| 14–16 cm | 36–38 mm | Aerolux 36, Crown Date 36, Santiko 38 |
| 16–18 cm | 38–40 mm | Santiko 38, Chronova 39, Aerolux 40, Crown Date 40, Daylux 40 |
| 18–20 cm | 40–41 mm | Daylux 40, Devaron 40, Nautora 40, Royal Frame 41 |
| over 20 cm | 41 mm | Royal Frame 41 |
The scale is a recommendation, not a rule. If you like a bigger watch on a slimmer wrist, wear it — all that matters is that the case doesn't hang over the edge of your wrist.
Strap length
Metal bracelet
Metal bracelets ship at full length, because they are sized by removing links. You can do that at home in a few minutes — we also sell a sizing tool kit that works with both screw-link and pin-link designs.
Leather and silicone straps
These adjust on the holes, so nothing needs shortening. The standard length suits most wrists. If yours is notably slimmer or larger, write to us before ordering and we'll tell you whether the strap will fit.
What else decides how a watch sits
Beyond the diameter, the lug spacing matters — where the strap leaves the case. The flatter your wrist, the larger a watch it carries without the case reaching past the edge. If you are between two sizes, draw both diameters on your wrist with a piece of string; 2 mm shows up more on the wrist than it does on a screen.
Frequently asked questions
What if the watch is the wrong size when it arrives?
You can return it within 30 days of delivery and we refund the full amount. Returns by post are free within Slovenia.
Can I change the strap later?
Yes. Every strap and bracelet we sell matches the lugs on our cases, so you can put leather, silicone or metal on the same watch whenever you like.
Which size is right for a woman's wrist?
Size follows the wrist, not the wearer — use the scale above. In practice most women land on 36 or 38 mm, but that is not a rule.
How precise does the measurement need to be?
Half a centimetre is precise enough. Differences within a centimetre make almost no difference to which case size suits you.
