Beautiful job. Every time I put it on, it amazes me that you can get a watch that looks this good for just $250.

Thanks for posting!! Just replaced my SNA411 crystal with a single-domed one from crystal times. Looks great and now I don’t have to worry about scratches on the glass! Couldn’t have done it without this video.

I'm so glad I saw this video, I never realized that crystal replacement is so simple and fairly cheap, and for me as a DIY type of person was a pleasure to gain some new skills, I used your link for purchasing sapphire crystal with clear AR coating, some 20 bucks for press tool and 30 for watch repair tool kit from aliexpress. I had my flightmaster for over 10 years and crystal had already a lot of scratches, in comparison to oem crystal, new one has a bit higher dome, it is not noticeable until you compare, old crystal was a bit cloudy especially when looking at the angle and looked yellowish. Sapphire is so much clearer and I can now especially notice shiny black dial finish, combined with new leather strap and butterfly clasp, I got same feeling like i just purchased new watch, just like 10 years ago.

My favourite Seiko watch Iv owned.

Thanks for this!! After watching a few times, I was able to swap in the same polarized AR sapphire in about 30 mins. I think it looks even better than the original!

Absolutely gorgeous upgrade!

Thanks! Just purchased the yellow/orange sapphire Crystal for my gold tone flighty.

Your video inspired me to do this to my Flightmaster. My crystal came in today and I swapped them out! Absolutely love it now!

Nice job, I have a domed sapphire for my 7t34 Flightmaster that I've not gotten around to doing yet.. this vid has helped spur me along.

Great video I followed your link and orderd a blue AR sapphire for my sna411p1 got my mate to fit it as he works with watches had it pressure test but his machine only goes to 100 meters test and it passed twice. Well happy in love with this great watch again

That’s stunning 😍. It’s crazy this same model has become more expensive. 😅

looks fantastic!!!

Looks awesome!!!

I just put a uncle Seiko president bracelet on my sna411. It is a nice step up from the original. After seeing your crystal change I think that’s next on the list.

畫龍點睛，好機芯好盤面好外圈這支錶再改上這個鏡面完美!!!

Beautiful! 😍

Nice good video, thank you! BTW from where did you get the leather strap shown in this video, looks really nice.

So funny, used EBay link for Glass, already on my watch-watch list

Man looks great, definitely tempted to change the glass on mine too. But Im worried about the water resistance, I'm a diver and I've taken my flightmaster 20 meters (65.6 feet) under water with no problem at all and I'm not sure I'd repeat that after the sapphire change.

Just ordered a crystal for mine. That was always the thing I liked least about it

Didn't test-rotate the bezel before assembly. Didn't test the pushers before assembly. Puffed air into the calibre inside the case ... which could force dust into the area between the face and crystal. Didn't use a plastic protective barrier between the case back tool and the case back.

Thanks for sharing your video. Great mod! If not a secret where did you buy a sapphire, brand/model, cost.. Thanks & Cheers

nice leather strap, is it 21mm ? great mod, I might do this on my flighty too.

👍

I have this model from 2005, about how much should I expect to pay a repair place to do this for me plus a battery replacement, Thanks so much

Gorgeous! Can you please leave a link where to purchase the crystal saphire for flighty?

If I buy the glass, would any watchmaker be willing to put this on? This looks really nice. Thanks for the vid!!!

I'd say if you're worried about scratching your sapphire crystal by using a cloth, maybe you're not sure it's sapphire. The inner coating i get, but the outside...that's the whole point of getting sapphire, isn't it?

Wow you got two models of the watch now you’re only missing the sna414

What size crystal did you use and where did you get it.

Nice Benchmade)

Great mod, well done, now to do mine. Polarized, blue or AR clear?... hmmm... The blue is barely visible in your other video. What music did you use on this one?

Cool. Why did you choose a dome glass?

AR coating never seems to work 😂. But I was curious about readability since part of what the hardlex does is to magnify the dial

I've got to say, after replacing my crystal with this one I miss the distortion of the original. I think I prefer single dome vs double dome.

Hey man, do you know if this crystal is AR coated on the underside only?

Can you please share the link to where you purchased that crystal? Thanks!

I heard somewhere that you'll lose the 200m water resistance if you change the glass , is it true ?

Looks excellent! Does this affect the water resistance?

Where did you get the cristal, I want to do the same for mine

Man that looks awesome. Is it likely to still remain waterproof?

Great looking mod, though it's possible to see that when looking at the watch from a shallow angle the new crystal significantly magnifies\increases the gap between the chapter ring and bezel, whereas the standard one keeps them tight and actually closes the gap a bit. Likely due to a different inner dome curve on the new crystal, it seems to NOT be the same exact dimensional spec as the original which changes the optics. It's possible to see this effect at 12:02 & 12:07. I wouldn't be surprised if some of the perceived reflection reduction is due to this difference as well as the AR. No, I don't use the bezel & chapter ring functions myself like 99.9% of owners, but it's worth making a point of as it's a detail that's important to some people regardless of actual usability. EDIT: Having looked into this a bit more, 100% sure the difference is because the Seiko crystal is single dome, the new one double dome.

Where did you get the sapphire glass? Model number?

What about the gasket for the crystal? Do you replace the gasket when you change the crystal?

Is the polarized version recommended?

Where do i look for this mod at where do i order sapphire crystal

Does the sapphire crystal have a blue tint?

Is there still distortion with this glass?

Song? lol

I need to mod mine were can I purchase this accessory?

Where can I buy the Sapphire crystal at

Where can I buy the same crystal?

looks cool but thats good bye to 200 meter resistance right there

What strap is this?

How do you remove the crown

Painful to watch
