On this forum communication is KEY.
We shall see.
As far as the original topic.
I will post the comparison shots and whatnots. I have a BK, ST(both 3135 and 3035) and TC case to compare. The BK is definitely thinner, but the crown position is too low. For the 16800, IMHO, nothing beats the 3035 case. If I had a Sean case it would be a full comparison test.
I will be comparing the Raffles rings, with the BK and the TC movement rings, as well as the back of the cases where the movement sits, etc... Lug width, profile width and so forth. I like the TC ring because I can secure it to the movement first, then slide the movement into place like a gen. The idea is not bad. Just need small holding tabs. I tried this on the TC case and worked well.
The TC build is a birthday present for someone. I will be using my current V2 16800 build in the comparison, and how I was able to fit a y3135 movement back there. Not too hard, but tricky. I also have the 16610 Yuki dial build on a y3135 using the ST3135 and this is a very nice build. everything fits the way it should, as well as the case having the correct dimensions for the 16610, including the cutout for the movement set screws being gen correct.
Back to the original post. Didn't mean to thread crap.
