An open cuff is not a bangle. It does not slide over the hand, and it is not meant to sit loose. It is shaped to hold itself against the wrist, and it can be adjusted to your arm — carefully, and rarely.
Putting it on
Hold the cuff with the opening facing your wrist, place the middle of it against the inside of the wrist first, then roll it around. Do not pull the two ends apart to push your hand through. That is what bends a cuff out of shape.
If the ends are pointing the wrong way once it is on, turn the cuff around the wrist rather than lifting it off.
Adjusting the fit
Only if it genuinely does not sit right, and only in small steps.
To make it tighter: hold the cuff in both hands, thumbs on the outside, and press the ends gently towards each other. Millimetres at a time. Try it on between each step.
To make it wider: the same movement in reverse. Do not lever the ends apart over the edge of a table — that puts all the force at one point and leaves a kink.
Bending the same spot back and forth repeatedly is what fatigues metal. Two or three careful adjustments over the life of a cuff are fine. Twenty are not.
Where it should sit
Just above the wrist bone, tight enough that it does not slide down over the hand when your arm hangs, loose enough to turn with a little resistance. If it leaves a mark, it is too tight.
Wider cuffs sit higher on the forearm, where the arm is more even. Our 30 mm cuffs look best 20 to 30 mm up from the wrist.
Which width for what
6 to 8 mm disappears under a sleeve and stacks well with a watch. This is the everyday width.
20 mm reads as jewellery rather than as a detail, and works on its own.
30 mm is the statement. Wear it alone, on a bare forearm, and let it do the work.
Taking it off
The same roll in reverse, then into the box or the pouch. Cuffs left in a bowl with other jewellery pick up scratches on the plating — that is where most of the wear on a cuff actually comes from.
