AP Novice - Carbon vs Ceramic vs Titanium

[marc2828]

Hello,
I have always wanted an AP Offshore. Looking at the 44mm Chronograph series. I would like a lightweight daily nice watch on a rubber strap. I find my manual wind Panerai and my SD43 not that comfortable to sleep/shower etc. I wear my Casio Protrek most of the time (solar, nuclear time set, light weight). The Casio is a great watch, but a bit beat up.

My questions for the forum:
1) what is the weight diff of the 44mm case in steel vs titanium vs carbon vs ceramic? I tried on a 44mm forged carbon fiber 26400AU.OO.A002CA.01. Felt awesome and light.
2) Any advantage/disadvantage of forged carbon fiber vs Titanium vs Ceramic cases in the AP 44mm line?
3) I am not loving the new wide pushers on the AP Chronos vs the older buttons like on the 26207IO.OO.A002CA.01 Sebastien Buemi model. Thoughts?
4) Thoughts on buying a limited production piece vs a non?

thanks in advance for your advice,
Marc
