T usually equals cash money!! Used in the A and some in the B series except for submersibles. Just another thing that harkens back to the history and gives the watch some Patina on the dial and markers.
Here is my old 1A, man I miss this watch and sold it before the prices went through the roof. Oh well, it went to a friend and a very good home.
The strap is a sick 26mm AMMO squeezed in, loved it.
