I bought a few watches recently, and two had link bracelets. They were both huge. I googled how to remove the links, sounded easy. It was impossible. So I decided to order the watch tool kit, to see if I could manage without paying a jeweler.  I read the reviews, and expected to take 15 min to remove one pin alone. It took less then 3 minutes to remove 3 links (4 pins ) and to replace 2 pins. Amazing. You just have to figure out how to do this by trial and error. It is pretty obvious what will work. Then go to it with caution.  I have previously purchased the tools to put the watch face back on after replacing batteries, since I have learned the hard way, I can not do it with out the press. Highly recommend. Arrives quickly, and saves you money. Batteries are much cheaper if you do it yourself, and if you buy your watch on line, expect to pay a jeweler to resize your band. Very happy with this purchase.
