Unscrew 1 or both of the bolts of the adapters. If you choose to unscrew just 1, the other one just unscrew slightly so it would be easier to work with or move. 2. Then insert the "L" shaped bar holders in the watch band's hole and make sure they connect to each other in the middle (male and female ends). 3. Put the base of the adapter back in the same position to match the holes, so you can then easily screw back on the bolts.<><> *The proper side of the adapter: Make sure before you tighten the bolts, the center security locking mechanism - the silver color Ellipse should be on the bottom of the band (the bottom will be 2 Black Ellipse and Silver color locking mechanism in the middle). The top of the adapter should be 3 equal Black Ellipses. *Its is very important the 3 Black Ellipses shapes of the adapter are always on top and face up when installed on the band. This way the locking center mechanism will lock the band to the watch case. If you put the adapter upside down, the adapter will not lock or it will get improperly stuck in the watch case. When you tighten or unscrew the bolts, do not use too much force because the bolts are small and micro sized. To unscrew the bolts - unscrew counter clockwise. To tighten the bolts - screw clockwise. When tightening , slowly and gently tighten until the bolt just stops turning. Don't use so much force because you will ruin the bolt head. !! Watches, Bands or Straps are Not Included !!
