. My 2 cents. the Fiddy has a special place in any collection.
For the sum the Fiddy is going for nowadays, a pre-A 1 would be much more appealing to me.

And don't get started about the pre-A 1, we won't have enough page to discuss it here 

Prices of both 127 and 217 are unbelievable right now but if money doesn't matter, both are such a nice watch to have. Regarding the 1A or 1BT...they are such a great model to have and the price of A-series are still acceptable. You won't regreat of having it in your collection.
Cheers
