Remove the veneer for the end blocks from the foil covered block. Trim it to pass around the watch bar. Note that there is a full hole for the watch bar and the front face (with overlapping edges) is separate from the back, which has no overlaps. It needs to cover then end lozenge when it is lightly touching the bar but must not be tight, otherwise rotation will be limited.
