Use common sense and wear protective gloves to prevent injuring yourself and demaging your watch. If you have just spent your life saving buying this watch I recommand buying a watch link removal tool.
Use a blanket on top of your work surface to protect your watch. Find a paper clip and a piler.
Look closely at the watch. You want to remove those links with arrow markings on them. Try to remove same number of links from both sides of the watch to balance the band length.
Use the piler to hold the paper clip and push into the pin hole in the direction of the arrow. Use a post-it pad under your watch. Use force and don't slip. Be careful.
The pin will come out from the other end.
After the whole pin is out, you will see a metal sleeve coming out the top section. This is the part that hold the pin in place.
Repeat the above procedure to remove another pins and links.
When ready to reconnect the band, put the sleeve back into the same place. Push the pin in opposite direction to the arrow. Use a post-it pad to push in the pin.
