I'm down for the BK/WM9 preorder - that is going to be a fantastic piece for sure - I'm thinking that is going to be the ultimate in the forseeable future.
I have a DRSD from Paso/MBW and it is superb too - wouldn't hesitate to pull the trigger there and Paso is a great guy to deal with.
However, if you're looking for a daily beater, it is hard to go past Trusty Ultimate SD 16600. I have a gen 16600 (in the safe now - it's a collector's item!) but wear my TT watch as a daily beater and it is a great watch. It looks perfect. Sure, if you put it side by side with a gen and break out the loupe, you'll notice some differences, but on your wrist, it is ideal. Trusty says it is waterproof to 100m and I've certainly worn it swimming without any problems. Been on my wrist for about 9 months and so far we're on average + 5 secs a day which IMOis respectable straight out of the box with no servicing/modding.
My 2c - put your name down for the WM9 and get a Trusty ultimate to wear for the next 9 months while you wait for the WM9 to arrive
