Watch Clasps Butterfly Deployment Clasps for Leather Watch Band

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.

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.

I was very skeptical of this deployant seeing as reddit and forums pan all cheap deployants. But this was so affordable I thought I'd give it a go. This deployant has a strong retention and I spent a few minutes trying to force it open without the pushers. That's to say, it definitely will stay closed! As far as comfort, the hinge area is well rounded and doesn't have much sharp edges so no problems there. The single piece design on the bottom also prevents skin grabbing. However, the stainless steel cover over the pushers (circled blue in the photo) is somewhat sharp. It's not sharp enough to be fully uncomfortable but it does make it's presence known occasionally. Thickness isn't too bad either. Overall, the clasp does its job protecting my leather strap and staying secured. It's fairly comfortable but not the most comfortable deployant I've used. But it was very cheap. Definitely worth a shot and no qualms putting this on my more expensive watches!

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.

I needed and ordered a 18mm. What i got was 18mm to 20mm universal clasp. It sits to wide and doesn't look good. The stap has to much side to side slop in it on the adjustable side. My picture of the 2 straps shows a true 18mm fit and its nice looking the other not nice at all

Omg. So first one didn't arrive. They shipped another next day. And I love this deployment buckle. Its better than the one i spent $300 for on my Panerai. Hats off on design

Corners of the clasps are very sharp and dig into your skin.

Easy to install and wears quite comfortably and looks sleek

I was expected to be disappointed, but I can happily report that this is a pretty good clasp! Works well on my Panerai and holds up to everyday wear. I haven't worn it too much, but around a month of everyday wear, while traveling and it still looks and works well! Hopefully it holds up!

On the more expensive side of available options, but the build quality is good. Would purchase from the same brand in the future

WoW , j’adore , facile à mettre en place , permet de protéger le cuir de la bande puisque on n’a pas à faire de manipulations pour l’ouvrir et la fermer et le meilleur de tout , la montre est sécurisé car même si on l’échappe pendant qu’on en en train de la mettre sur notre poignée, elle ne tombera pas à terre puisque une fois la boucle mise en place , la montre devient comme un "bracelet".

The buckle arrived on time however it has a different mechanism compared to the advertised photo. There is no release spring as shown in the photo so the buckle doesn’t pop open and need to be opened manually. I had ordered this item specifically for the release springs. The photos shared by other reviewers seem to have the release spring, so the seller might have sent a wrong item or using old photos for the advertisement. Extremely disappointing! I wouldn’t recommend this item.

Excellent, looks good and comes with a complete set of spare bars and a tool for installation/removal
