ubiquitous Posted July 17, 2009 Report Share Posted July 17, 2009 Mrs. Ubi has an uncanny knack for busting up watches; not even a month after picking up this J12 for her and she's already managed to crack the bezel insert I bought her a new J12, but figured this old one could be a good parts donor. So, I decided to dismantle the case to see what I could salvage. 3 piece sandwich construction- Cool! The bezel/crystal and movement are all one component: And the caseback seats to this unit, thus providing the sealing to the case: The mid case ring sits in between: Unfortunately, upon closer inspection I discover that the mid case is a write off: Nice fracture going right through the lug end... But it is indeed solid ceramic! Let's hope Mrs. Ubi goes a little easier with the new one when it gets here. I am somewhat relieved that this happened to a $250 rep and not a $4k gen!

jmarin.72 Posted July 17, 2009 Report Share Posted July 17, 2009 I am still trying to figure out how did you two guys managed to pair together!!! it must be a yin and yang thing i guess... or as they say...opposites attract!!! Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted July 17, 2009 Author Report Share Posted July 17, 2009 Heh... Well, we've been a pair for 11 years now and going strong Aside from how she takes care of watches in comparison to how I care for mine, we're really quite similar Quote Link to comment Share on other sites More sharing options...

Samurai Posted July 17, 2009 Report Share Posted July 17, 2009 Am surprised the ceramic cracked. Isn't it supposed to be like a really strong material? Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted July 17, 2009 Author Report Share Posted July 17, 2009 Well, we know that the ceramic is pretty well resistant to scratching; perhaps this added rigidity makes for a case that is more prone to cracking as a result of it's rigidity? To point out a similarity- Let's look at crystals. Acrylic crystals are soft and quite easy to scratch- Just looking at them could cause a scratch However, if you were to drop it, the acrylic seems to be able to absorb that impact better because it's relatively soft. Sapphire on the other hand is also resistant to scratching like ceramic, but is more prone to shattering; I imagine there's more tension in the rigidity. At least, that's my theory on the matter...

vlydog Posted July 17, 2009 Report Share Posted July 17, 2009 I imagine there's more tension in the rigidity. This is true with most of the people I know too. Great post Ubi! Quote Link to comment Share on other sites More sharing options...
Jkay Posted July 17, 2009 Report Share Posted July 17, 2009 Am surprised the ceramic cracked. Isn't it supposed to be like a really strong material? If she hit it hard enough to shatter a bezel, she hit it hard enough to crack that thin part of the case. It must have been a very strong whack.
