How to Install a Deployant Clasp

In this video we show you how to install a deployant clasp on a watch that already has a standard prong buckle. It's a very simple procedure, and requires a minimal amount of tools.
Deployant clasps are shown here: www.longisland...
Calipers and spring bar tools can be found here: www.longisland...

Also helps eliminate dropping your watch when you take it off

And if you ever end up a grifters mark, they won't be able to slip it off your wrist

I have bought 3-4 of these deployant clasps from Long Island Watch and 2-3 from Amazon. I can tell you there is no question in the quality and finishing. The LIW ones are ready to go out of the "box". They are smooth and comfortable with no uncomfortable edges. The amazon ones, while a little more inexpensive, are full of sharp edged and all have needed additional attention to make them comfortable. The Amazon clasps really lack the refinement that the LIW ones have. I end up sitting at computer or TV and using a fine nail file board to radius all the edges on the buttons, frame, buckle side, the strap side. It takes 30-45 minutes plus PER deployant clasp. To me that is not worth saving $10 per clasp. I will only buy the LIW ones from now on. In full disclosure, I don't know Mark, have never met Mark and am just an occasional customer of Long Island Watch. This was written to hopefully save you the headache I ended up with when ordering cheap. Thx, Joe

I’ve bought some 3$ ones on AliExpress, so far so good

Thanks alot because i just bought a watch with this type of band and had no idea how to work it lol.

Just purchased a Michel Herbilin Newport Trophy watch (with deployment clasp). Had some trouble with the clasp at first. After watching this video I finally managed to figure it out! Thanks.

Just bought a Bulova watch that came with a deployant clasp....nice...but I didn't know how to tighten the band. Thanks for your video. Easy peezy...now off to buy my wife a deployant clasp for her watch band. Helpful video. Thank you.

Not only I understand how to operate this kind of clasp now, I also know why it is used👍🏻👌🏻. Even 5 year old vid has value 😊

[@zhenguo3620]

Thanks for making this video. I didn't know anything about deployant clasps before but I was googling hidden buckles for leather watches and this was the first result. Really clear instructions, and nice close up video.

[@BrianBlakley]

Very helpful video. I have hated the leather bands on most of my watches and replaced them with metal bracelets which are much easier to put on and take off. Maybe this will let me put the leather bands back on some of my watches again. Thanks!

You are most welcome.

I had to revisit your excellent video here 5 years on after my leather strap finally died today. Ever grateful to you given the absolutely useless videos on YT on this topic elsewhere!

[@kato223]

One thing to keep in mind, the "U" end that you attach to the buckle end of your band, sometimes you have to shave the band down a bit to make it fit. I have several resin bands that I had to do this to so the clasp would actually attach. Other than that, I am 100% all about deployant clasps helping the bands last way longer!

[@terryjones5339]

Just ordered replacement leather band and deployant clasp. This video will be extremely helpful when I install the new band. Thanks you very much. Great video and narrative.

Hello Marc, --AGAIN-- When the student is ready, the teacher appears! This demonstration/tutorial is VERY helpful, --and (several years after you produced it), --it's "TIMELY" ;-) Thank you and timeless best wishes!

Nicely done! Without watching your demonstration, I would not have been able to buckle my JBW deployant buckle. Thanks.

Mark, you are a genius! I am a high school teacher of 15 years, and a huge fan of how you deliver your lessons. I will only make my seiko and orient watch purchases through your store if only for your brilliant customer service and educational model. Thanks for making me interested in watches. Btw, I’d love to get my wife an Orient Soma for her birthday next year, I’ve noticed that you don’t carry those in your store. Any suggestions as to where I could get one? Or, will your store be carrying those any time soon?

Thanks Marc...I purchased two leather straps for my Invicta Pro Divers for wearing in the summer. I'm so getting those buckles upgraded now...Thanks again.

Sounds like a good plan.

Great instructional video. I am pretty mechanically inclined, normally, but this thing was making me crazy! It so happens that I own a carbon fiber, digital caliper that I picked up on Amazon for well under $10.00. That's in case you don't order on from this gentleman.

Fabulous ! I've been looking at other KZbin butterfly clasp videos and I still could not figure out how to open the butterfly clasp installed on a strap I bought. Yours mentioned "it's called a double push-button deployant 'cause it has two buttons on it ....", and eureka ! Darn, why don't other videos mention it, grrr. Thanks, problem solved !

[@josho.9530]

You helped me put on my new movado haha, never had a bracelet-style before. Thank you!

[@tarquesh]

Perfect vid. I bought a watch with butterfly lock for the firsttime in my life, but the watch seller adjust the strap to loose. So by the vid i’d adjust the strap, and my new watch fits perfectly on my wrist. Normaly i have the famous pin buckle, and of course a strap will be worn out quicly. I not know that you can put the strap without bending in the first lug., so it is saving my crocodile strap for a while. My other watch is also suited with a crocodile strap, so maybe i will put a butterfly lock on it to. I have also a watch with calfskin.

[@Clyne69]

I hate how the clasp doesn’t sit in the middle of my wrist

[@smbmostfamous1432]

i have a cheaper version of the clasp, been having it for 6 years already and it sits perfectly on my bottom wrist.. i guess it all depends!!

Just got one of these off eBay for a couple bucks, got it, and saw the bar in the other end where you feed the strap through- I thought it was blocking the strap from going through!! lol.. didn't realize it opened up and the little bar went through the hole. Duh!! Thought mine was defective haha.

[@aussie8114]

But later in the day when your wrist swells you have to resize it. A normal buckle you simply slide it into the next hole without removing the watch from your wrist. I think the secret is to use a leather that is nice and soft that will bend easily. I got one such strap from WatchGecko straps called Paladina buffalo grain. Extremely soft and comfy though I did replace the buckle for a bit better quality one. The buckles they use are a bit cheap looking. Or for a really comfy nato option try a Vario elastic nylon strap.

Is there such thing as a clasp that does not require the use of holes? I have a problem finding the right fit using the holes. I have a normal watch band I like with holes and am wondering if it’s possible to modify it with a different clasp, similar to how Breitling clasps work without holes.

[@malthus101]

I'm buying a strap and there is an option for "no holes" - how would the depolyant clasp be adjusted if the strap had no holes?

[@Trex100]

Thanks!

[@oldgeordiegeezer3086]

Excellent - I sat down to browse to find exactly this. I have a smart watch with a leather strap and antennas sewn inside the strap so I cant change the strap. I also have a couple of other watches with leather straps that I would like to "convert". Where can I get these?

[@thomaslinton1001]

"Deployant" is "deployment" in French. We are to use Franch in future when speaking of watches? Or just an affectation?

[@bbrachman]

Can you show a video on how to cut the watch band down to size for the deployant clasp? I want to make my own watch bands (leather) and use one of these.

[@paul64774]

Hi Mark. Only just seen this video. Great video. When ordering it asks for size 18-20-22. Is that the buckle end (that you attach the clasp to) and NOT the lug size correct? Thanks. Paul (UK).
