Looks great! One suggestion, shorten the tail of the second hand to get closer to the gen spec. See you went for the Helanarou insert. It's a real pity they didn't make the numerals slightly bigger as the serifs are cool. My build says hi too.
Looks good! If you wanted to go the 700 route, Athaya has crown and tube sets: http://www.rwgforum.net/topic/175678-fs-rolex-700-crown-and-tube-replacement-09mm-stem/
Gen on the right:
Agree. It is the best option for T19 Superdome. In my opinion a better look than the Clark & Sternkreuz T19s. I have tried both those too. The Clark made the Rehaut look too large on my Cartel, and the Sternkreuz was a loose fit. This is what the MY T19 looks like on a Cartel case with a Yuki dial.
Dial dots are slightly distorted head-on, contemplating taking a little off the height to see if it improves the situation.
