I am considering buying a 103. The two models that speak most to me are the Ti TESTAF and the Ti DIAPAL (older version with black bezel). Since both models are no longer in production, I will be buying a pre-owned watch.
I am interested in hearing from forum members regarding which model they would choose. I would also be very interested in learning about what forum members think about DIAPAL and the benefits of this feature over the regular movement.
