JLC could give a more important depht rating, but it would have required a sapphire ( no way on this piece ), or a different plexy, not shaped in the same way, less nicely integrated to the bezel.
The original one was WR to 155 meters.
As for the comparative prices of the TT DSA and TT P, this is very subjective, indeed.
The TTP used a well known case, the Amvox I, and was developed with the same crowns.
On the TT DSA, the case, the crowns, the dials, the plexy, all is different.
Priced a bit too high?
I can understand that, but to me, it was even worst for the TT P.
Best, my friend, and yes, see you soonb in Geneva.
I will be there on Monday morning, by the way.
Nicolas.
