@ Lobster,
Are you an alias for Nik, or are you just shilling for him?
M,
A Taka crystal is going to be much cheaper than an IWC saphire.
He has them ready to purchase, so you don't need to send and wait for yours to be done.
You can sell the rep crystal on this forum.
Ditto tomhorn about VAC.
And since you are not going to do a movement sway, I would suggest that you send your hands, too.
The lume will be consistent ... very nice touch.
I think Vac may do the DDW, too.
If not, there are some other guys who are more than capable.
If you decide to go with IWC parts, and since you are "in the middle of USA", PM me.
You will not have to worry about Customs issues.
Keep us posted on your project,
Mike
