Adjusting the length of the silicone strap
1.
release the silicone band from the clasp. to do so, use the pointed end of
the band replacement tool to push the spring bar out of the fastener. the
other side of the spring bar can be removed while the fastener is open,
enabling you to remove the silicone band.
2. using a knife or scissors, cut the silicone band in the middle between two
metal pins. You should shorten the band symmetrically and little by little,
starting from the clasp, until you have reached the desired length. test the
length from time to time before proceeding. Shortening both ends by the
length of one metal pin results in a total difference of 10 mm in the length
of the strap; shortening one end reduces the length by 5 mm.
3. remove the first metal pin and replace it with the spring bar. then
reattach the clasp to the band.
