Invicta watches, like many other watches, may be a good fit for some as-is. For many Invicta owners, however, the bracelet or band on the watch will need to be resized for a proper fit. One option is to take your watch into a watch dealer or a repair store to have some of the links removed. For you, though, it might be a more appropriate option to remove some links at home to shorten the bracelet to the appropriate size.
Lay the watch down on an area that is flat and has been cleared of clutter to ensure that you don't lose any of the pieces of your watch.
Use the watch link removal tool or safety pin to remove the clasp from the rest of the watch band. The clasp is attached with a spring-loaded pin so you don't want to push it all the way out--just enough to allow you to remove the band.
Use the watch pin removal tool or the safety pin to push the pin for the last link on the bracelet. Take note of the back of the band to see which way to remove the pins. There will be arrows on the backs of the individual links that indicate which way the pin should be removed.
Continue removing as many links from the end of the bracelet until you've shortened it to the appropriate size.
Attach the clasp firmly back to the watch bracelet by pushing the spring-loaded pin back in, the opposite way you pushed to remove it. Once the pin is back in place, you will feel or hear a faint click and the pin won't be sticking out on either side of the clasp.
