Classic sub, just get a TC and a gen insert.
You're really not gonna be able to improve on that too much without getting a bunch of gen parts.
I do think TC subs would look a lot better with lug holes :lol:
Hell, I'm considering selling a few pieces and getting one.
I was was not a big fan of subs when I first got in to reps but after getting a decent 16610, it's really all I wear. That and my modded 1680.
I've been slowly trying to get started on a 16800 like Mitch's but cases available today just don't cut it.
if it was gonna be a cheap build or even just a modded rep, i would be game but practically everything for a 16800 is custom/gen. I'm glad Mitch told me this before I started. My original plan was to get a TC mid case, get holes drilled and pop a 16800 dial in there. Lol. I've learned that it's not that easy.
There are plenty of rolex experts on this forum that will teach you about things you never even noticed before. Once you notice them, you can't unnotice them.
If you haven't already, go to the rolex section and read everything you can about the model you wanna build.
