Frequently Asked Questions

What is a half-link? A shorter bracelet link that provides finer length adjustment than a standard full link.

Can I install half-links myself? Possible with the right tools, but most people prefer a watchmaker to avoid damaging pins or the clasp.

Do half-links affect the look? Slightly – they are shorter, so the pattern changes a little near the clasp. Most people find the better fit worth it.

What if my bracelet has a micro-adjust clasp? You may not need half-links at all. Micro-adjust systems already give fine control.
