I bought a watch for my daughter on Ebay from China and this needed to be adjusted. Mr Jules said we would need to take it to a jeweller to be done, but I Googled and found a site and between me and my daughter we managed to do it ourselves. There are little arrows almost unnoticeable until you are looking for them and this is the direction the pin needs to be pushed in to slide out, you can pull the pin out using tweezers or fine pliers and remove the section, it is just a case of taking out how ever many is necessary and then putting the pin back to join it together again, I think we took out about 4 links, but my daughter is a teenager so you might not have to remove so many. Hope this helps.
