Explaining The Types Of Domed Sapphire Crystal Replacements - Watch and Learn #52

[@huanquatro]

I think I like single dome crystals the best. The crystal is just another equally important piece to a watch, and so I like to see its influence.

[@Paul-up3pb]

You’re very good at what you do (articulate, no BS, knowledgeable, and kind.) Thank you. 👍 I’ve purchased 2 watches from you and your customer service is very good as well!

[@islandwatch]

Thanks so much Paul.

[@mikefreedom8881]

Totally agree! And also made 2 purchases and can vouch for that too. Was actually just telling my friend that this was the Goulet Pen kinda service and similar great personalities (Brian Goulet, the face of Goulet Pens) for those of you that are also happen to be into fountain pens lol

[@VictoriaStobbie]

I chuckled when you’re like “amazing how you find these things” then I read the text.

[@bruceleroy8063]

Truth is truth

[@paulr1917]

A great video to demonstrate EXACTLY what I was curious about! The structure and optical effects of flat, dome, and double dome. Thanks!

[@davidgarciagarrido129]

No magnification without representation! Excellent video as always. Greetings from Spain

[@Mikishots]

I'm always surprised at the substantial thickness of these crystals. Great vid, very clear presentation!

[@deedee8568]

Haven't found this explanation elsewhere, so, thank you and super helpful.

[@danieldelorme4021]

Amazing video! The magnification of a single dome and the distance was exactly what I wanted to see. Very informative. Thank you!

[@salty_terminal_civilian5374]

Marc, I love when I search for something related to watches you have a video. I'm on your site right now buying crystals and I search up single vs double, and here you are with a video. Thanks.

[@artieshell9205]

Great and succinct explanation. Thanks!!

[@arimorrison7816]

this video is fantastic! Perfect explanation

[@ErikS-]

As can be expected from Marc, it is again an excellent video. If there is a “watch professor”, it is for sure Marc.

[@pabloorellana7631]

Very informative and useful video, thank you

[@SonnetGomes]

Thank you. Great explanation. I actually love the distortion the double dome produces.

[@ReiMonCoH]

Dude... seriously, I’m just getting into watches. I feel guilty I’m not paying for these lessons. This info is solid gold. Thank you for posting 👍🏻

[@WrongTimeWatch]

Wow, I really like that Squale. The Orange and brown looks good.

[@islandwatch]

It sure is cool looking.

[@kingreese808]

SUPER helpful!! Thanks Mark!!

[@divindave6117]

Thank you for this video as well as others, which explains what stuff is. Your channel is saving me a lot of time searching for information. For What Its Worth, I think your watch reviews are the best, and Ive seen a lit of them. Very down to earth and you explain the features very well.

[@jimcombs9121]

Really enjoy learning about watches from Marc. Seems like when I google how to do something with a watch a video of his pops up in my searches. Lol! I even bought a Orient Kamasu coin bezel adaptor Long Island Watch created recently and love the product and how it made me love my Orient even more.

[@Leonoscarr]

Great video. I’m glad I watched it

[@drwindsurf]

Thank you Mark. Missed this video when you released it, and it is super useful - I always thought double domed was convex on both sides (wrong). Thank you for educating me :)

[@wendigee]

Good video thank, very well explained finally!

[@ThisIsDavesGarage]

Single dome for vintage style watches! It mimics classic acrylic crystal distortion. Double dome for modern style watches. Thanks for the explanation Mark

[@JahStyles]

Thank you Mark. Love your videos, very informative and relevant!

[@Wolfpacker]

great explanation as I'm trying to decide what to order.

[@hippoo25]

Deciding to mod my skx011. This is SOOOOOO helpful!!

[@7imonUP]

Hi Mark! This video was very informative and fun to watch! I also want to thank you for being so professional on email. I was the person who's srpb41 cocktail got stolen by the customs. Thank you one million times. I'm definitely going to buy my next watch from you.

[@islandwatch]

Hope the next one makes it!!!

[@7imonUP]

Long Island Watch hope so to! It's in Sweden now!

[@georuiz74]

Really helpful - thank you :)

[@julianneale6128]

Excellent explanation, thank you!

[@MTCKIE68]

I've been waiting for you to do this video for a while. You gave me what I needed to know and see. Thank You. !! Always Love these learning videos you do.

[@islandwatch]

Thanks for taking the time!

[@brandonsuire9601]

I just purchased a custom watch case with Saphire lens. Now I know another layer to the topic. Thank you !

[@carlosgonzalez7204]

Very cool. Thank you for the information!

[@jeffuhl763]

I really enjoy your videos. Very informative and easy to understand. This one was just what I needed to know. Thank you!

[@dandaniel5225]

Random piece of paper routine was funny. Thanks again for this and all your videos.

[@korbendallas9722]

Great video. That domed sapphire crystal sure is a nice upgrade.

[@islandwatch]

It sure is!

[@marshallcollins8634]

Thanks for splaining it for me. I knew there was a double/single dome but I didn't know EXACTLY what that meant,if that makes any sense. Once again great video. You must have been a teacher in your other life.

[@allisonsmith9050]

Awesome vid!

[@sarfarazshaikh771]

What to say again & again, mark you rock with your videos, keep up the work 👍

[@islandwatch]

Thanks! I will!!!!

[@johnrb9397]

Single dome for the win!

[@FouseQuentin]

I believe there's another difference : if you've got a single dome and a double dôme with blue AR and you look at the watch at certain angle on single dôme you can clearly see a flash of the blue AR while on the double dome the AR coloring won't be seen as much. Let me know what you think about this.

[@MrTw2009]

Great video. I can't tell if I like single or double better!

[@bernard4007]

that explanation about the double-dome was super helpful...just the information I was looking for....thanks!

[@boxsterh]

Thanks! Appreciate the simple video explaining the differences. I've been thinking of upgrading my Mako II with saphire, and this better explains my options.

[@islandwatch]

You are very welcome.

[@BrianBlakley]

Another excellent and informative video. Thanks!

[@islandwatch]

Thank you.

[@roberts.4582]

Very educational, as always. Not sure why two people have given this video a thumbs-down. Are they documentary filmmakers or something? I guess even gifts make some people unhappy.

[@danielfigueroa6294]

Thanks for the demonstration. I knew the difference between double domed and single domed but never had the opportunity to compared.

[@islandwatch]

Thanks for watching.

[@cashau2965]

nice vid Mark...thanks and keep 'em coming

[@islandwatch]

welcome!

[@JohnClarkW]

Nice demonstration Marc. I can't say why, but I have always liked the distortion from single domed, even if the double domed is generally considered better.

[@islandwatch]

I think I do agree with you.

[@safirouhi1651]

Thank you for this. Had I not seen this video I would almost definitely have, at some point in my life, bought a double domed sapphire crystal thinking it caused extra distortion (which I like) and been in for a rude surprise

[@Nefville]

Basically everything I know about watches comes from this series, I wish Marc would do more of these or redo some old ones.

[@lskovly]

Great and informative video Mark!!

[@islandwatch]

Thank you!

[@karls5474]

Thanks Mark for another informative video. I've learned a lot from watching your series.

[@dieper76]

Excelent explanation!!!

[@chinawatchshop]

great content, like

[@KakashiHatake-ou7mp]

Very useful! Thanks for this video!!

[@islandwatch]

Welcome!

[@LSUfan]

Fantastic video.

[@fluffyfreak505]

Im a single dome kinda guy. Like the random peice of paper you found blowing around out there in Montauk!

[@islandwatch]

LOL, thank you.

[@DrDan-ue9de]

Thanks for the great explanation!

[@garrettjones6272]

Great video, No BS and very informative

[@evaninnewport]

really interesting vid mark. thank you

[@islandwatch]

Thanks!

[@tonyholmes198]

Great vid Marc, very informative.

[@islandwatch]

Thanks Tony.

[@jasonhermosilla9064]

Awesome video!

[@islandwatch]

Thanks so much.

[@dga223]

Great explanation.

[@stattersall]

I have analysis paralysis and can't decide which of the three to get... I have put so many different combos in my long island cart, but I just can't pick. I'm driving myself crazy, but loving your videos.

[@thearcanearcade4923]

This guy's got a great sense of humour.

[@lukaszM46]

very good explenation, the only thing that's missing is how the light is reflected in the two types of domed crystals, as you get different reflection images with them.

[@rogerlyonsjr9302]

Kudos. I like your channel and your store. You try to give people what they want, which is a bit like reading the stocks. However you are good at it. I like that you offer components to people who want to do their own mod. work, or offer products that you've modified yourself.( Love that Orient ) I'll be ordering an Orient, strap, and a sapphire crystal in a few days. I've been an employee for various companies over the last forty years. It's nice to see you tell the " big guy" thanks, but no thanks, I don't need to depend on you now, good day. Your work ethic is good. You're prompt with your customers, try to give them an idea of what is the best for their money through your YT channel. A truly difficult task requiring extensive knowledge of your products. You also are courteous. An important but often disregarded part of a transaction. The phrase " A pleasure doing business with you " fits here nicely.

[@Tennisfiles]

Thanks Mark! My SK007 that I got from LIW got condensation in it (probably my fault) and I was looking into upgrading the crystal and possibly the movement which doesn't work anymore. This was very helpful. Thanks!!

[@powertube5671]

Excellent video. I was surprised that the double convex lens had no magnification and I actually studied optics in college! But, that was back in the late 60s. Excellent demo! Not a bit boring.

[@islandwatch]

It's a blast from the past.

[@roybaker6970]

The inner dome is concave with the same radius of curvature, cancelling out nearly all the front surface magnification.

[@AZ-if2mj]

Your understanding from college was correct, the DD crystal is a meniscus: convex top, concave bottom. If convex on both sides (biconvex) then it would magnify about twice as fast than the single dome (plano convex). Meniscus lenses are often used for aberration correction from the difference between the side 1 and side 2 radii.

[@gotsouced4943]

I like ar coating and single domed. I like distortion of lens it adds a cool look even if it's a diver.

[@Staggo_L]

Excellent video. I should have known you have the answers.

[@mocha8232]

Great video!!

[@paulx7620]

Great vid thanks

[@winduncan9818]

Thanks, I was just on LIW site and didn't know the difference or which to order

[@ivermec-tin666]

Re: AR coating. I see a clear AR option and a blue AR option. Are these comparable in quality and function? Would there be any visible difference on a double dome sapphire crystal, as I understand the blue flash does not occur on a double dome? On a flat sapphire crystal, I assume that there would be a flash from the blue, but not from the clear. Optics fascinate and confuse me. Thank you for splaining how a double dome crystal works optically.

[@davidw4278]

I am now a fan of double domes.

[@abdull1154]

Hey Mark always love the video. Curious to ask what type of crystal is on the 6105 captain willard have?

[@hassananzar7433]

Mark, LOVE YOUR CHANNEL. I am getting on in age and getting nearsighted So I installed Cyclopses on all my Flat crystal date watches. Can ya show me how much Magnification a Single Dome actually gives on a standard watch. I just wanna see how much magnification we can get from them. Dun mind forking the extra 40$ but I wanna keep my watches

[@mrpipspoppersv9093]

I like the single dome best I have one on my Hamilton khaki I like the magnification.

[@islandwatch]

See, something for everyone!

[@1947froggy]

Question not about dome, but maybe you can answer. I was looking for a sapphire crystal 3mm for my watch (I dropped & broke it). Could only find up to 2.5mm. In mineral glass I found the 3.0mm. Is there a reson for this? Thanks, subbed. Enjoy the channel.

[@xubairhanif963]

I used to think double domed has more curvature then single domed.. great video

[@islandwatch]

It can, or it doesn't have to. It's all in the underside curvature.

[@bounbone]

Thanks Mark....

[@islandwatch]

You are welcome.

[@itsalgud1459]

Thanks!

[@deotan6294]

Hi, if you have double dome what type of ceramic insert should I get?

[@MrShinobi797]

Good content Marc. Would you kindly take time to explain sometime, “ Sapphire Coated ” or “ Diamond Coated ” Crystals and exactly HOW this is achieved?? Thanks!!

[@islandwatch]

I think that's mostly gimmick, with limited additional hardness.

[@phildobz375]

Can the slim dome fit on a regular bezel?

[@Namegoeshere-op9hg]

Crystal thickness…besides pressure, does it matter? Does it affect magnification?

[@markvalender]

hi very interesting and well explained. however does the double dome have convex or concave on the back?

[@ctrip34]

What if you were to do a single dome inverted? Like upside down. Would that help with distortion?

[@muhammadshafiq661]

For clarification purpose, flat and double domed have almost the same distortion and the only difference between them is the dome itself?

[@islandwatch]

Yes!!!!

[@davidsonviray1403]

Is the single domed is like i "raised" sapphire crystal on a watch?

[@DarthJabba504]

Great video! I wonder what the reflective properties are between these, I've heard flat has too much reflection, which a dome addresses. Does that mean the distortion people love in Omega Speedmaster acrylic crystal is more from the shape than the material???

[@Itsshowtimecheer]

How do you decide the crystal thickness? If too thick the crystal pertrudes higher than the bezel and if too thin it creates a trench for dirt. I am asking for my SRPB53, which a am looking to buy a double dome for.

[@vidpro4422]

So the side with the rough edge goes into the case first or vice versa?

[@AD.TV_Mecha-Fresh]

Hey Marc where would be a good place to find a crystal replacement for Citizen watches?

[@armandogomez2677]

Dumb question thinking of upgrading my samauri is there a reason you not double dome is offered and on the double dome does it matter which way I install it?

[@Gary-ib8dz]

Thank you for another informative video. I was wondering about this topic a couple weeks ago. Do you think you'll ever get the Orient Analyst back in stock. I bought a 2 tone one from you for my dad. I always thought I'd buy an all silver colored one for myself one day, but now I can't find one.

[@islandwatch]

I would hope so, it was a hot item.

[@ranillorodriguez6807]

Hello, are the double dome crystals size for an SKX007/009 the same as for Seiko Monster? thank you!

[@fatcatpeople]

Quick question I have a caliber 6N42. Is there a caliber I can upgrade it to.

[@misternobody4644]

Great video! One question, which has the least amount of reflections/glare without AR coating?

[@islandwatch]

Flat
