Adjust a Casio S 935L Watch Band

The Casio S-935L and S-1171L watch bands are initially a bit complicated if you want to know how the adjustment works. But a little effort reveals how amazingly simple adjusting your Casio actually is.

Steps

  1. On the inside of the band, locate the links with the arrow etched on them. The arrows mark the removable links.
  2. Lay the watch on its side on a flat surface with the arrows pointing downward. Be sure to leave about {{safesubst:#invoke:convert|convert}} of space between the bottom of each removable link and the flat surface.
  3. Using a 1/32" flat head jeweller's screwdriver (or metric size 1.0), insert the tip of the screwdriver into one side of the removable links' pin holes. You will find that the pins have an end that looks like a screw head. This is misleading - press down very firmly on the other end.
  4. Press downward firmly to make the pin pop out the other side. Be careful not to lose it.
  5. Remove the pin on the other side of the arrow-marked link.
  6. Repeat as necessary to remove half the needed links. You will remove the other half from the other side of the band to maintain equal band length.
  7. Flip the watch over so the arrows are pointing upward.
  8. Align the holes in the remaining links.
  9. Insert the rounded edge of one of the pins into the open link hole. The pin will go in without trouble until the top.
  10. Holding the pin in place, carefully flip the watch over again and firmly push the pin fully into placing using the flat surface. The pin will snap into place.
  11. Repeat for the other half of the band as necessary.

Tips

  • Use a hard flat surface.
  • Don't poke yourself with the screwdriver.

Warnings

  • Note that the metal band of the WVA-470 model looks exactly the same as that shown above, but there is a very tiny (3mm) sleeve that fits into the center section and provides the friction that holds the pin in place. DO NOT LOSE THIS! If you don't replace it, the pin will just fall through when you put the pin back in. The friction sleeve only goes back into the center section one way -- the proper end has to go into the proper side of the center section.
  • Be very careful when using the screwdriver as you may poke yourself instead of the watch.
