So I got the diver from Andrew at Trusty Time on Tuesday. As per, the transaction was flawless, and the watch got to me a week after I placed the order. The watch looks superb and feels well made, keeps time well (though the rotor on the movement is very noisy, it seems the bearing is of poor quality and makes quite a racket).
Going back to the original topic of this thread, one of the reasons I bought the watch was to use as a dive watch. I decided to have a look inside.
I started by taking the 8 screws off the bottom of the case. These were not tightened very well, so lesson number one is if you are planning to taking this watch anywhere near water make sure to check that these are not loose.
Once I got them out I took off the case back to find a greased rubber gasket on the case back. As a precaution I re-greased the gasket with some silicone grease that I normally use on my underwater camera and torch o-rings.
Next I removed the 8 mini-nuts that hold the hexagonal bolts and the ceramic bezel and the front glass in place. Upon taking the ceramic bezel off I discovered that bezel was cracked at the nuts in at least 3 places, similar to what is described by olreon in his post here http://www.rwgforum.net/topic/158555-carbon-diver-on-trustytime/page-8. I believe this to be due partly due to the lack of rubber mini-gaskets on the bolts (gen has them), so when tightened the metal on ceramic pressure simply cracks the bezel. I believe this can be solved by the manufacturer by including these mini gaskets in. In terms of water resistance, these gaskets stop the water from getting into a space below the bezel and corroding the bolts. This would be quite relevant if you are going to expose the watch to salt water which is quite corrosive. Having said that since the movement is sealed by the front glass which has an additional rubber gasket, this issue with the bolts does not affect the water resistance of the watch.
Taking the front glass off, on the underside I found a well placed rubber gasket (though this one was quite dry). I greased it with silicon, checked for dust and re-assembled the watch. Throughout the process I did not take out the movement, as there really was not need for it.
Once done I greased the gaskets on both crowns, and dropped the watch into a glass of water to sit overnight. Next morning I check the watch and it seems to have passed this initial test. I will take it diving over the next couple of weeks to see how it holds up at depth over a period of 1-2 hours. Having taken the watch apart however I must say that something like a Rolex Submariner should make a more reliable dive companion, as it has far fewer potential failure points than this AP. As such I think I might splash out on a Sub (possibly even a gen).
Hope you guys find this useful. Will keep you posted on further developments.
