Depending on the age of the watch you will see indicators of pin direction on the inside of the band. Little arrows that point the direction the pins should come out. If there are no arrows you can look at the edge of the band. You are looking for a split in the pin that makes it look like a screw. The opposite side will be solid. You want to push on the side that is solid so the side that looked split comes out. This is a cotter pin and the split side is bigger and needs to come out first. Use a small punch to push the pins out. Make sure you take links from the band evenly on either side.

You may or may not have arrows inside bracelet. Arrows are pointing the way the pins must come out.
First you have to find out what sort of pins or even screws are used to keep links together.
Examine both bracelet sides and find the side where pin ends have a groove.
Start with a tiny screwdriver and unscrew one of the screws. If it turns, but doesn't come out, that means you have a pins instead.
For removing pins the best would be pin removing tool (approx.5GBP on ebay), but it's possible to do the job without it.
Take a hardened steel needle and blunt the sharp end to the approx. size of pin end diameter using any sharpening stone or sandpaper. Get an old towel and fold it to make a soft base for work (like small cusion). As you don't have a special bracelet holder you will need a pair of helping hands to hold the bracelet steady upright. You will need small hammer and pair of flat nose pliers as well.
NOTE: The pins MUST be driven split end out first, not vice versa. Make sure that the grooved pin ends are facing towel, not the needle and hammer!!!
Now place the watch on the folded towel, take that needle and smallest hammer you have and start driving the pin out using light blows. Do Not hit hard, as you will brake the needle, scratch your watch or even injure yourself. Watchmakers are using 45 gram hammer, so, calculate your strength of blows.
After a few blows check if the split end is coming out and when you see that the end is long enough to grab it with pliers, pull the pin out with pliers. When pulling, do NOT turn pliers, as pins tend to brake when twisted. Use firm grip and your strength to pull the pin without twisting.
After shortening the bracelet or adding extra link(s) make sure that the pins go back EXACTLY the same way as they came out- the blunt end first in the hole and the split (grooved) end last. Before doing that check remaining pins in bracelet to make sure that you put them back from the right side of bracelet.
It is recommended to use plastic hammer to drive pins back in or you will scratch or damage bracelet. If plastic hammer is not available use an old toothbrush handle (or some plastic item) as an absorber. Simply put pin into the hole as deep as you can with your fingers, put the toothbrush handle on split pin end and hit handle, not the pin.
Make sure that pin ends are flush with bracelet. If needed- hit few more times.
Job done!
If you do not want to do it yourself, any jeweler will do it in a matter of few minutes.

You need a link tool. You can purchase this item on Ebay or watch parts sites. Some have a little track that you put the band on and screw a pin into the pin on the band and it pushes the split pin out and you remove the link. Pay attention to the pins on the band. You need to push out the side with the split pin that looks like a flathead screw. It sometimes is. In most cases it is a pin. When the link is removed you have to connect to the next link and push the pin into the hole again and it shoul go in the direction of the other pins. The pin should go in on the side with the split looking pins. You will need special tools: pin pusher device, a pin block and hammer with pins to hammer out the pins on the band usually. Some or most folks take classes to learn this but you may be handy and figure it out.

I was able to take use a push pin (thumb tack) to get out the (split) pin. I put the thumb tack in the hole of the pin I wanted to remove, place the thumb tack upside down on our counter top and gently but firmly push the pin out. It only has to push out an 1/8 of an inch and then you can pull it the rest of the way. Thanks to the diagram that "guest" posted above - I copied and pasted: http://www.pmwf.com/Watches/WatchSchool/WS%2014%20How%20to%20Resize%20Common%20Bracelets/WS%2014%20How%20to%20Resize%20Bracelets.htm#Split%20pin%20bracelets in the browser and it showed me how the pins work in the wrist band. Didn't need all of the fancy tools. (:
