Things you will need, small paperclip, small pairing knife.Fig. 1 shows the layout of it being assembled. But before that, take the small paper clip where the clasp and pins connect on your watch, and push pin through. ( All through this process remember this step, Keeping your fingers /thumb near by to keep the pin from shooting out where it will most likely get lost.) Once paperclip has push pin from it's socket, slightly pull at band so to get pin from it hole. Keeping pressure on band, and pin offset from hole, remove paperclip. There should be a "click" when paperclip separates from clasp, this is because the pin wants to slide back in hole, this is why pressure is pulled on band. "This is where the pin can fly out". If possible try to re-use the Factory pins if not to bad worn.Now back to Fig. 1 Recheck to make sure you have right size, if so move on to next step. Take pin and insert it in hole of the "Notched or Smaller flange" of new add-on clasp. It should look like Fig.1 "A". Make sure the "collars" of the pins are protruding on both sides of the new clasp. in Fig 1, A.Once again when joining these two clasp together, it may be snug, don't bend parts to much or the pins will be damaged. But once it has fitted together it will look like Fig. 2, B.Now for all the pins, make sure! That they seat well. This is a new part which is an add-on, it's going to be snug at first so make sure the pins seat in holes like in Fig. 3, C. You may have to take the pairing knife and nudge pins around a bit to get them to line up properly.- Closing. These little add-on clasp has been a saver. I've had them in the past, and they are hard to find with the Jeweler stores for some reason. I guess they want to sell a watch or even $30.00 band links.-If your not sure on what size your band is, look on Amazon for a Digital Caliber. I bought a cheap one for less than 10 bucks. If you're like me I can always use this somewhere........Ok great I hope this helps someone on this purchase here. I am not affiliated with the seller at all. Just someone who wants to help.

Definitely did the trick for my Citizen 1481010 jump hour. Those Japen only release watches come with really small bracelets. Looks like it came with it

My clasp is exactly 23.96mm wide. I ordered the 24mm extension, assuming it would match up to a 24mm clasp. NOPE! The 24mm extender actually measures 25mm and will not connect the clasp at all.

i like how easy it was to install, and the fact that it permits meto wear a favorite watch that i had not been able to wear because theband was too short.

The extensor worked. The two spring bars didn’t. In position, they wouldn’t extend enough through the narrow spaced flanges to go thru the mating holes. I had to pay a watchmaker for a spring bar that worked (I used one from my watch for the other end).

I got this to make the Seiko SARB033/SARB035 bracelet fit better. This little piece did EXACTLY what I needed it to do. The bracelet fits great now. If you're in the same situation, get it.Update: I’ve now purchased this item TWICE. Great product that meets a need. Fantastic customer service as well. Recommended!

This works perfectly on my Wenger band that I lost the links to. It was easy to install and matches the band just fine. Try this before you buy a replacement band that you might not like.

Vintage Seiko bracelets often don’t include all the links, and many of them weren’t very long to begin with. So it’s fairly common — especially for the JDM (Japanese Domestic Speed-Timer) versions — to use an extender with these bracelets. This extender is pretty basic, but it does the job. Like another reviewer states, the metal isn’t all that thick, and it’s not exquisitely finished. But it doesn’t look terrible and it gets the job done.
