Sapphire crystal install on Casio Duro (plus strap swap) (Duro Mods)

[@mikeellis4345]

Thanks for the video! I just changed my duro over to a domed blue AR sapphire crystal. It looks fabulous. The only issue I had was getting the crown and stem out. It went back in easily enough later. Next project will be a ceramic bezel insert if I can find a nice one. Cheers mike

Very nice mod and although the sapphire crystal is not far from the price of the watch, it’s well worth the extra cost. I have the black and gold Duro on a Bond Nato strap and it’s a seriously nice, unpretentious watch but would love it even more if they made it in 40mm. I wish that all watches had a sapphire crystal and I’m sure that most watch enthusiasts would pay the extra for sapphire.

[@watchinout8832]

I agree with you, if it were a 40mm case it would be unbeatable. And yeah I think it’s worth then investment for the sapphire despite the price.. plus you can always get the $18 piece of sapphire from AliExpress instead

[@luckybiby8968]

The flat sapphire reflected less glare from the partial ceiling lighting, the dome sapphire captured the reflection of the whole ceiling lighting, the glare was too bright. Flat one is better. Thanks for the demo!

Great video. As an amateur watchmaker, I'm enjoying your channel. One suggestion is to also replace the crystal gasket when replacing the crystal if you want to maintain the original water resistance rating. If that is not a concern, then reusing the original crystal gasket should be fine.

[@otte]

Is there a gasket for the crystal on this watch? Saw a lot of these crystal replacements no gasket mentioned.

[@mtbbiker6401]

@@otte I haven't done a Duro, but I've done a bunch of other watches. There has to be a gasket otherwise there's no way it could be rated at 200 meters. The gasket is usually a plastic ring that sits in the case. You never see them on videos because they never remove the rotating bezel in order to access the crystal gasket. Honestly I would never trust the water resistance after a crystal replacement unless the correct crystal size and gasket size are used and then only after a water resistance test. If you don't plan to swim, then no big deal.

@@mtbbiker6401 would never swim with them.

@@mtbbiker6401 Maybe buy some to be sure.

[@mtbbiker6401]

@@otte If you don't plan to swim with the watch, then don't worry about replacing the crystal gasket. That would require you to remove the bezel which isn't the easiest thing to do.

Had to put the AliExpress flat sapphire in my Duro due to my clumsiness dropping it face down on the ceramic tile bathroom floor and smashing the mineral crystal. Had it done by a local jeweler as it was cheaper than buying all the tools to do it myself. Although the sapphire and repair equaled the price of the watch, it was worth it as I'm quite fond of Duros.

Also the marlin Duro is no longer made so it's best to preserve it.

[@jltrem]

@@mikeyKnows_ That depends where you live. It’s still available in the U. S.

[@mikeyKnows_]

@@jltrem true, I just bought the blue Duro but it's what was already made all the new manufacturing is without it. I will get me a few more before the stock runs completely dry.

[@jltrem]

@@mikeyKnows_ I have the gold also.

​@@jltremand about waterproof?is there any ORING or glue?

[@benlittlechilds1192]

Would love to know where to get cheap yacht style bezal inserts? I did the pink sapphire on my duro and love it!

[@andresorts]

Hello, my Casio marlin duro has lasted me a week, I have scratched the glass and the aluminum bezel, in your video I have learned how to change the glass for another and it is fantastic, but I can't find ceramic bezels of the exact size, could you tell me where to find it?

[@louislombardelli1691]

how does that press work if the crystal has a magnifier over the date ?

[@nkk-b]

Was that a single domed or double domed crystal

[@daviddrew7624]

I see you didn't change the crystal seal, will it still be waterproof, also any idea where I can get a replacement bezel insert for a casio duro mtd 1054 / 102 many thanks dave

Bro where u get the lens??

What is the size specs of the sapphire crystal?

No problem. Thanks for Watchin!

[@whitesonar]

Thanks broher

[@christian_zns]

Thanks for your explanation. I have two questions. How can i be sure that it is still waterproof 200m after the swap? What masurements does the crystal need to fit the duro?

[@watchinout8832]

There’s really no way to be 100% sure that it will still hold up to it’s water resistance rating, but as long as you put some silicone oil on the O ring, it should be more than fine to swim with. The measurements I don’t have on hand. Check out the “Just one more watch” channel. He has a video of this crystal swap as well, and I believe he has measurements. Or take a look at the crystal size in the link that I posted

@@watchinout8832 alright. Thank you very much for the help!

Whats the size of sapphire

Hi, what is the size of the Sapphire glass here pls?

32.7mm

@@otte thanks👍

[@stevekennedy2337]

Any tips on how to get the stem back in? I can’t seem to get it.

[@watchinout8832]

If the movement is seated properly then the stem should go right back in no problem. It has to be lined up perfectly though. Definitely don’t force the stem. Keep fiddling with the movement carefully until you can properly slide the stem back in

[@stevekennedy2337]

@@watchinout8832 awesome thanks a lot..😀😀

[@adamjensen8112]

put an automatic or mechanical movement in it next. true sleeper build.

[@Soudchaser91q41]

Le verre saphir OK mais je crois que le nouveau bracelet est encore plus laid que celui d'origine. Mais c'est compliqué sur une Duro car on ne peut pas mettre trop cher pour être cohérent avec l'esprit de cette montre.

[@ymad29]

C’est surtout un bracelet en cuir sur une montre de plongée c’est n’importe quoi

[@yambo59]

Buys the watch pad then lays the watch with new crystal face down on the table...???

[@gsxr2fst498]

Get a nato strap

[@grneal26]

I don't understand the blue or red AR coating, Why not get a clear AR coating so you can truly enjoy the dial without a red or blue tint?

[@grneal26]

same. never understood the appeal of blue or red.
