Montblanc Dual Carbon Process Testing Part 1

 

A few pictures of the case to document its condition before we start testing the Dual carbon coating.

It is black but is extremely polished, very different than the PVD coating on the PPro ABR.

This case was rejected by Montblanc's QI team because of cosmetic issues.  A close look demonstrates why...the DLC coating did not make its way into the area between the lugs and case.  It also looks like there may be a little rust at the bottom of the spring bar holes under high magnification.

 

This was noticed at all four lugs.  Notice the double spring bar holes in the lugs.  This not only provides extra security but was designed so  the strap could hug close to the case.  I guess this also means that customers will need to source their straps directly from Montblanc (not that I can imagine any other suitable color combination for this watch except for black) or else the extra hole would be visible under close inspection.

Notice the thickness of the numbers on the bezel...we'll see if this holds up under the testing.

Interestingly the DLC coating was perfect in between the chronograph actuators and the crown.  The polished surfact is vunerable to fingerprints!

Recessed luminescent pearl

Overall an extremely attractive case in my humble opinion.

A solid back also coated using the Dual Carbon process.  Notice the two different finishes

Taking the case back off reveals no coating on the inside surface but the rim demonstrates that the case back was exposed to the heat during the hardening process.

The areas where rubber gaskets would be set to provide the Sports chronograph with 20Bar water resistance.  The chronograph be functionned at that depth too.

 

The sapphire crystal is flat.  The magnifying window is located at the 3 oclock position. 

I think it was press fitted.  I didnot see any rubber gaskets between the crystal and case.

A now for a sneak preview of the testing which will take place this week

Cheers,
