Welcome Rahbari ...
to our Chopard Forum and Congrats for your Pro One.
Our friends had given you all the answers to your initial questions, thanks to all of them.
As for the hacking feature, the later L.U.C 96H24 in the Pro One GMT has it.
May not be appropriate to have a sapphire caseback for a rating of 300m, in case some use it for diving. Perhaps L.U.C
could consider having the rating marked on the caseback instead, giving the option of below 100m rating with a sapphire caseback
and anything above, then the solid caseback 
For your timing, could you fully wind the Pro One by manually turning the crown for about 90 turns, and check the daily-rating again.
If it is still at -15s/day, you should sent in to be looked at.

In love with Pro One... but minor issues
Hello, I am new to this forum! Last year I virtually fell in love with the Pro One with orange markers. The case, the dial and - last but not least - the strap are just breathtaking! As I am still a student had to look out for a good second-hand watch and...
Some Answers For You
Hopefully I can help you out, at least a little! I have owned the Pro One four times (don't ask!!) and currently own the same version as yours. Plus, I own other watches with LUC movements. First, here is a post of my Pro One which you can compare to your...
What he said
I have a Sport 2000, which has the same movement as the ProOne, but with a display back. Even watching the spring barrel turn as I wind I can't hear or feel any feedback through the crown. A
Welcome to the Club
The Pro-One was also my introduction to the Chopard LUC series. I have it now for 3 or 4 years and I still like it very much. Yes we all know about the loose bezel, but mine is pritty tight now (only if I put my hand in the pocket, it might shift a notch)...
Thank you for replies!
Thank you so much for your replies! Glad to hear that my watch is in normal condition! I have worn the watch over the whole weekend and am thrilled by its looks! However, it is a pity that Chopard did not manage to make it a perfect watch in every way: IM...

Agree with Kong...
On the rate issue. Most likely your watch is at least 3 years old, probably older and in need of a service. If fully winding the watch doesn't help I suggest you send it in. Chopard will probably install the later improved tighter bezel at that time. Than...
