Hey all, I spoke to Edvi at ABC today. Really nice guy! We were talking about crystals and I mentioned that one of my crystals has no surface scratched but in certain light angles you can see what look like hairline cracks/scratches embedded in the plastic. He mentioned that this has a name "craze". And so I learned something new today. He mentioned that this is actually something that some vintage enthusiasts actually search for and want. How interesting!

So how about you guys? What are your thoughts on craze?

Im not sure about collectors wanting craze...I like my crystals vintage, but not into them full of craze.

springer · 17 April 2014, 10:27 AM

cdweller · 17 April 2014, 10:34 AM

Naw, it's like having vintage tires on a vintage car. Not good in my opinion

007Sub · 17 April 2014, 10:52 AM

I would have thought the same but he told me that he has been getting folks asking for crystals with craze more and more. Sounds cray.... But maybe craze will soon be the new craze?! Hah

Not for me.

greekbum · 17 April 2014, 11:51 AM

This happens from heating up an old crystal via a polishing wheel to take out scratches. Somewhere i have a dozen or so super domes that look like the galaxy is in them...lol.

V.lats97nsx · 17 April 2014, 11:59 AM

I have a chip in my crystal. None of that craze your talking bout.

I prefer a clean plexi but dont have a problem with the crazed ones as long as they still pass a pressure test.

NukeMan · 17 April 2014, 07:13 PM

Yep, agree to the above. I findi t difficult to see that a lot of collectors really want craze (as with spider-webbing of dials), but to each his own I guess.

Darlinboy · 17 April 2014, 07:32 PM

I'd be looking for a replacement crystal if I saw that.

Tudor66 · 17 April 2014, 07:45 PM

That's not something I seek out in a vintage, but to each his own

MonBK · 17 April 2014, 07:46 PM

Replace

dysondiver · 17 April 2014, 08:22 PM

yep ,,, thats not a feature ,, its a fault.
time for a new crystal ,, lesson there about old crystals and polishing wheels ,, just put the time in by hand , or be very careful. nice sub though.

andromeda160 · 17 April 2014, 09:03 PM

My crystal on my 72 oyster precision had a lot of small cracks in the crystal, looked down one day and one of the crazes turned into a full hairline fracture by a slight bump against something. You'd have to be craze-y to keep one on.

linesiders · 17 April 2014, 10:30 PM

Craze is to Crystal

as

Dry Rot is to Tires

If it was the original crystal in a 50 year old watch I might leave it, but only if it was staying in the safe.

I have had that on a crystal before - though no idea or reason to believe it was from polishing with a wheel - that I listed as failed and recommended replacement to the purchaser.

Mendota · 17 April 2014, 11:22 PM

My wife's Volvo XC90 headlight housings have the identical crazing. They are superfine cracks. It is a symptom of improper use of a buffing wheel on a plastic part. Hand polishing does not generate the level of heat needed to produce these hairline cracks. There is no way to repair it. Replace it. This is a defect and it will fail on you when subjected to extreme temp swings or pressure, i.e. swimming.

Nice sub, otherwise!

subtona · 17 April 2014, 11:34 PM

Dials can show crazing
Crystals can show crazing
And during a fire, glass can show crazing from the heat build up, large crazing from a slow build up of heat and small crazing from a fast build up of heat...

Generally speaking, crazing is not sought after.

watchcrank · 17 April 2014, 11:55 PM

Pass on that :-)

sryukon · 18 April 2014, 11:32 AM

Yes I had a vintage Fortis with no craze I hand polished the crystal and after a few hours on the beach in the hot sun wala instant craze :( I think the heat built up under the thin over polished crystal and crazed up the crystal not good imo
