totally agree
by burying the case under ground is cool but i wondering what does it really test? i am sure the case has good water resistance characteristic specially from reputable brand such as mont blanc. can we do some test on the new high tech DLC please? thank you for your extra terrific effort to do the test. cheers! 
Field testing the Montblanc Dual Carbon Diamond Like Coating--Part 3
Last year I received a sample case from Montblanc to test its proprietary Dual Carbon Diamond Like Coating process : click here I completed several tests, but here is the results of the final examination. (I'll be releasing the results of the interval tes...
5 months buried in the ground
Nice test and glad to see the Montblanc DLC coating to be fine and no moisture in the case. Have you considered attaching a strap and then wearing the empty watch case and then shooting video of you blatantly banging the watch against the wall, door, tabl...
Even better... I designed my own version of the "Fleuritest"
Here is a hint: Cheers, Mike...
I hope you strapped it on Colby for an entire week :)
That would be THE ultimate test on the durability of the DLC coating! - AT
I am very curious on your "Fleuritest" ...
Colby and Spiderman! Can't be that straight-forward strapping to Colby... what are you thinking? Indeed, what were you thinking - putting spiders on a birthday cake! Did they frighten Colby? Kong PS : Incidentally, there will be a new certification coming...
Hmmm....
This would be a good science project for Colby someday. How much abuse can a DLC coated watch-case withstand? Hypothesis: a large amount of thermal stress abuse Testing procedures; PuristSPro MKT33 Standard Guidelines Conclusion: DLC Coating withstands a ...

Guys....watch it
if you have time....this movie should have the answer of CVD prosses to produce DLC coating. Artificial diamond is even harder than natural one, keep them away from your wife's diamond ring!!! LOL You can start from 1/5 of this series. For those busy peop...
MB Dual Carbon DLC coating test
Very cool test Mike! Impressive that there's no corrosion after 5 months buried in the pond in freezing temperatures. It survived mother nature perfectly, let's see how the case holds up after getting banged around by the kids. Looking forward to a few ma...
Thanks Mike for the long 'field test' !
Ha! I was wondering where was DLC casing you have. What an idea you got leaving it outside to weather the extreme mother nature. Come on, get a really hard metal and scratch it ! Its a real thrill Kong
Great post.
It looks like the DLC treatment really does the job. Good test. Thanks for sharing. Vte
Great report on the Montblanc Dual Carbon
I would love to see the macro pictures to see how, if there is any, the pitting effected case. You hand a complete enclosure and nothing seeped in. Pretty cool. Looking forward to the next part. Bill
Terrific "natural" test, Mike :-)
I recall that post too - it was a nice report on how he found the watch and had it serviced: "I recalled a post in the Chopard forum about a Purist who had lost his watch, only to find it 5 months later in a flower bed". Regards, Marcelo
I was wondering what happened to that case.
So you kept it wet and buried for months! Glad you could find it. I can't say I'm particularly surprised at the results. DLC is effectively corrosion proof in those conditions - cold, in freshwater (don't know the ph....), lack of oxygen. I'd be intereste...
Actually I was thinking along the same lines
when I placed the case into the overflow pond...I just wanted to see how the DLC coating would handle the usually harsh winter environment. It got covered by leaves and silt over the past 5 months. I'll take some pics of the interface for you. And yes, th...
Super interesting post, Mike!
I think the scratch test will be the real clincher, however! Montblanc may have developed a great coating. Looking forward to learning more. Thanks, Mike! Cheers, Daos
5 months is too short, Mike.
If MB's DLC can survive the scratch, it can withstand the winter coolness. But I am not sure about the result after 1-2 years it is left in the wild. Anyway, good idea for the test. Regards Ling
Looking good so far!
Thank you for the exhaustive tests Mike! Looking forward to reading about the other tests!
