Upgrading to a Sapphire Crystal on the Seiko SKX007 Dive Watch – Watch and Learn #27
In today’s episode of watch and learn, we will show you how to upgrade the hardlex crystal on the Seiko SKX007 to a scratch resistant sapphire crystal. It’s a simple upgrade that requires just a few tools and a bit of know-how.
The same technique applies to many Seiko divers, such as the SKX009, SKX173, SKX175, etc. The aftermarket is full of options to upgrade your Seiko diver, so this is just the start!

Do you know if they sell a sapphire Crystal with a cyclops. I have a Sub and love the cyclops but I wear my Seiko every day with no stress of scratch or dinging the bracelet or case
Great job, have you made afterwards a waterproof test to check if the watch has the same level of atm.?
Does it lose water resistance when you switch the glass? Are there any 39mm-38mm islander divers…?
thank you marc for sharing this with us. I have a Seiko franken monster watch which has the hardlex glass, it now has a little scratch on it. I used to rate the hardlex glass but no longer do. I have 10 -11 watches which are sapphire glass, you can’t go wrong with sapphire as their the 2nd hardest to diamond…. I also have anti reflective on my new le jour mark 1 chronograph watch. I watched a video that states you can scratch the anti reflective coating leaving people thinking that their sapphire glass is scratched which is not the case as sapphire glass can not be scratched, only the AR coating….
next time please do an oil filled progress for any water resistant watch
Personal note (just happened) remove the bezel if you have a ceramic insert. The crystal replacement came out great, but I shattered the bezel insert. Oops
im sure i bought one already modded and tested from you guys as a shop fitted mod , yes it was a seiko 007 , it leaked in a bathtub 12 inches of water !
Can you do it with bracelet still on
The other guys like Lume Shot would lubricate gaskets for an hour. This one was short and sweet!
Hi. Can I use crystal lift tool after I remove the bezel or this is the only way for diver watch
I want to put a sapphire crystal on my watch but I can’t. : (
That’s a very cheap crystal press but it appears to be doing a good job. What is your take on how effective these cheap presses are compared to the higher price tools?
thanks for the video. Is the crystal removal process for the Seiko ssc017 solar diver be the same as for the skx? thx
Is there a sapphire upgrade for the Citizen Promaster? You know, NY0040
thank you! i am really madness with SKX 007!! Still trying to buy one of this!!
I legit cringed when you popped the movement out
that was cool
doesn’t it lose it’s 200m water resistance after this? opening and reopening the case?
if it does you can’t use the watch in the water swimming etc also can’t call the watch a diver after this and that sucks ;/
those garden variety gloves shed a lot of lint?!
you positive that it’s ok?
Hi Mark,
One that is avaliable on your website is 2.9mm thick, 31.5mm
https://www.longislandwatch.com/Flat_Sapphire_Crystal_for_SKX007_SKX009_p/007-flat.html mentioned as OEM crystal size.
What is the source for the original crystal size?
Regards
Couldn’t you just pop the bezel off and do it? More work that way?
Epic : 2 sicko black dial
Brother : understanding
Good day .
How much does this effect the water resistance if at all? Any tips to help preserve water resistance after removing and replacing the glass?
Nice.
In Mark we trust, not the other guys who mod and cheat us on the video…
Hey do you have any idea if you’ll sell sapphire crystals for gen 4 Monsters?
Great tutorial!!! Needed to show how to make sure the crystal is clean from any dust before putting back the movement and case. Thanks
Great video with excellent tutorial! Will be attempting this soon on my Seiko flightmaster.
I replaced my crystal with a double-domed sapphire and it didn’t make that popping sound when I pressed it it, although I used a rather big amount of force. Should I put it back in the press and use even more force? You didn’t seem to need all that much…
Just to be sure, finally the waterproof resistance was compromised or not?
Hello sir
I have seiko 5 automatic I don’t know the model number the serial number is 874553 movement number is 7009 and case number is 838A. Sir I need single dome shappire glass with inner rubber and hour hands and sweep hand kindly suggests
the hardest part I think I’ll struggle with is getting the right crystal size XD
Me I greasse a crystal gasket?
Thanks for the explanation. Two questions if I may:
Is there a recess in the bezel for the crystal gasket?
When ordering a crystal gasket, should the inner diameter of the gasket be on size with the crystal, or slightly smaller. Reason I’m asking is that none of the gaskets from my supplier are on the size with (any) crystal. They have odd sizes, like not in half mm steps as the crystals are.
Thanks
Great video. I need to replace a damaged mineral crystal. Local repair shops want more than the watch is worth for the repair.
Just changed my Crystal to sapphire great instructions but it was difficult to see the place to ouch to get the crown out I also changed the aluminium bezel insert for a ceramic one in dark blue. Well pleased looks well smart and expensive. The sapphire really catches the light.
Would you change a watch crown for me?
Hi! Is it bad for my SKX to stop/sit during a day/date change? I mean when the watch runs out of power and isn’t being used and stops in the midst of flipping the date.
Easy job, will done this on my srpe57, wish me luck , thanks for the tutorial Marc!
I watch your videos . I just purchased a seiko SKX013. I want a new movement to install in it. Can you tell me the seiko movement part number that is automatic and selfwinding that I need to order.
Do you know of any maker of Sapphire crystals for a Graf Zeppelin Hindenburg LZ129? The plastic crystal has me insecure about it’s lifespan…
You didn’t align the chapter ring. Kind of an important thing to do.
Pressed down where you pressed but crown still won’t come out.
Thank you so much for these videos Marc. You make it look so easy. I’ve managed to pop a sapphire top hat into my 5KX. Was a bit sketchy putting the movement and crown back in but I managed it. Thank you Marc! Keep up the brilliant work and videos! Peace ✌
Do you know where I can get the exact crystal measurements for my Invicta 8926OB Pro Diver watch? I’ve had it for five years, it still keeps time great but the mineral crystal and aluminum bezel insert are getting pretty beat up. Suggestions welcome!
Im doing this on a duro with a double dome sapphire crystal
Here is the cool Alpinist mod. Check it out.
