Hymmm - actually if you want to be correct then "out of the box" would more than likely be BK due to better dial, slightly better SEL, better insert and white date wheel. TC has better crown height, cannon pin (hand height from dial) and strap has hollow mid links but that's an easy fix. Crystal is really 6 and half a dozen. The fix's mentioned that TC is working on (as i understand) are SEL, date wheel and pearl and when these are done I have no doubt that these will make a big difference.
The water resistant thing is [censored] as they are both capable of being very good in this area - more to do with the care that goes into construction.
