Diver with mineral glass? Is that not contradictory?

RD965How do you mean? I've had my Mako down around 100 ft a few times with no issues. These watches stand up just fine to recreational diving.

sw126687Well sand and other materials could scratch the glass more easily? that is my only concern really

RD965It's come up on various watch forums before. The Orient Ray/Mako aren't technically true ISO-certified diver watches. They say it's safe for skin diving, but it has notable missing components and points of failure for it not to be a true dive watch. I would classify this more as a "desk diver" for casual/office environments.
I own a Mako, the Ray didn't exist when I bought it. The only difference between the two being the dial. If I had to take a guess, I would say the watches probably fail the ISO 6425 standard (at least from my observations) due to:
1) Poor lume (It's not bad per-say, but it's not great either. The standard calls for it be very visible at depth, in darkness, at 25cm). Also there is no indication in total darkness that the watch could still be functioning (usually indicated with a lume pip on the second hand -- either on the tip or at the opposite end, which is generally extended somewhat). 2) The quick set date switch. While not flimsy, it's not very robust either. I can totally see it potentially failing (or even possibly unscrewing) at higher pressure failing tests.
EDIT: I also wanted to note that you should STILL be OK for casual diving. If you're actually worried about the mineral glass component, you can always buy an aftermarket crystal. I actually bought a sapphire crystal replacement from yobokies (seikoboy). There are pictures from Oldecrow on Watchuseek with some pictures. http://forums.watchuseek.com/f21/look-sapphire-orient-mako-cem6500-307867.html

Soundprank... Hope Everyone keeps in mind, That Although a more Expensive material - Sapphire, is more Scratch Resistant. It Can Shatter, easier than Mineral Glass, which is Tougher. Apple's hype on the Qualities and Use of Sapphire, is Misinformation.

RoaroftheTigerThe yobokies sapphire crystal is domed, and not flat, which is also the way the OEM crystal sits. Domed having specific qualities to help mitigate impact damage and shattering, but cna be more prone to scratching.
At least on the watches I've owned, those having mineral glass seem at a huge disadvantage, especially for those having domed mineral crystals -- regardless of shattering concerns. Unless you work around heavy machinery or something of that nature, I'd still suggest sapphire crystals outright.
The mineral crystal on this watch though, isn't one of bad quality. I've had my Mako pretty much as a beater watch, and it's only recently had some scratches to it that are noticeable (and only because I brushed against a concrete wall when I wasn't paying attention).
