By carefully pressing on the first links next to the lugs, you can adjust the IWC bracelet for smaller wrists. From the factory, the first links have a limited rotational freedom (intended by the designer to make the watch better suited for large wrists, see the left side). But after pressing carefully and with not too much pressure down on those links (see the right side) following the red arrows, the bracelet will fit skinny 6.5 inch wrists too.
