Watch Clasp, Butterfly Deployment Clasp Watch Buckle Replacement for Leather Watch Band

Picked up a couple of these butterfly clasps in 20mm and 18mm for a Casio Pilot and a Sea-Gull 1963! Great fit after easy install and adjustment. Very pleased with the look, price and performance. Will update reliability after wearing it over time.

What can I say, it works! It has never become unfastened while wearing so that means it does what it is supposed to. A few things though, when you unfasten it, the spring is pretty aggressive but that's really a minor issue. It also has a bit of bulk, but otherwise for this price point, who am I to complain when it does what it is made to.

Best option available on Amazon. Tight closure, no accidental openings

I've been told that all Amazon deployant clasps are terrible, so I was hesitant to try this out. I looked for one that seemed to have authentic reviews and settled on this one. Let me tell, you...I'm very impressed. In the closed position, this clasp does not rattle or make any noises AT ALL. The mechanism locks very securely, and no matter how much I contort my wrist I can't get it to fail or come unlocked. The side buttons don't rattle either and feel very solid. When unlocking the deployant the button have very positive feedback and the mechanism opens with authority. The polished finish on the clasp is done quite well and doesn't look cheap or low quality at all. I am now using this with my Oris Big Crown Pointer Date, and I think it looks right at home. I'll never buy a $60 deployant clasp again! Just ordered 2 more of these.

Easy to install (I am a jeweler and have experience) and kit was nice to have included. Clasp functions as intended. However, the clasp does open itself frequently. I use this watch for work and I've found myself having to re-close it several times a day. The watch has almost fallen off completely as a result a few times now; fortunately I caught it in my hand first. Not sure if I got a bad apple.Professional recommendation: if not sure how to install take to local jeweler to be safe and not ruin your watch band

I bought several Vellsar butterfly clasps in 18mm and 20mm, and the build quality is consistently impressive. The clasp feels exceptionally sturdy and secure. It has tight tolerance and very little play/wiggle on the joints, unlike the other flimsy and wobbly butterfly clasps I’ve tried. It has a satisfyingly strong spring action when opening and tactile click when closing. The finish is smooth on the entire clasp, and free of blemishes and irritating sharp edges.I wish it came in more finishes like brushed/satin, as well as a black and gold. Also, it has a slightly thicker profile which might be less appealing to those seeking for a low profile option.

This deployment clasp is something you see on higher end watches, and it’s a really nice addition to your favorite leather band watch.The deployment clasp helps keep your leather from wearing out, and there isn’t so much strain on the leather from pulling it to take the watch on/off like a traditional leather watch band.Took me maybe 5-10 minutes to install. I recommend buying a cheap watch repair kit set so you have some tools to help with install. My only complaint is that I seem to have to really push down when latching the clasp, and it doesn’t seem to hold too strong. It seems to be strong, but I can’t help feeling like if I were to accidentally snag my band on something that it would undo the clasp.Time will tell. Overall, for the price point, this is a great addition to your favorite leather band watch!

I purchased 2 of these to replace the originals on a couple watch straps where the butterfly constantly kept opening. So far they are working well, with not a single issue. You get everything you need to replace your existing clasp and the install is quick and easy.
