The Polaris

1. Work out how many links to remove. Each link is roughly 5 mm. Take the same number from both sides of the clasp so it stays centred on your wrist.
2. Find the holes, not the seams. Turn the strap on its edge. Each side link shows two small holes, set in from its ends — that is where the pins sit.
3. Press the pin straight in. Put the supplied tool into the hole and push square to the strap. One pin runs the full width, so the hole on the opposite edge is the same pin.
4. Ease the two halves apart. Keep the pressure on and separate them sideways rather than pulling lengthways.
5. Release the second pin. Each link is held at both ends, so repeat at the next hole along to free it completely.
6. Close the strap up. Line the ends up, press the pin, push together until it seats, then tug firmly from both ends before wearing.

Work over a cloth so a loose pin cannot roll away, and keep the removed links with the tool. If a pin will not move under steady pressure, stop — a jeweller will do it on a bench block without marking the titanium.
