I own both versions, asian and ultimate. I can tell you the ultimate I got from angus is definitley alot better watch. The quality of the strap is WHOLE lot better. The double a\r in itself, to me, is worth the difference in price. Plus the ultimate doesn't have that noisy winding sound.
I have never understood why the makers went to the trouble on the asian version of painting the CHOPARD on the deployment clasp, when the ultimate and gen do not have that. They actually go an extra step to make it not like the gen...LOL...
The case back and sticker issues people complain about don't mean that much to me, personally. I have several gen's, and in the last 8 yrs of owning them, no one has ever ask me to take my watch off so they can inspect the back. Even if they did, I doubt they would know the difference.
All I can tell you the strap, a\r, and feel of the ultimate Gran Turismo XL is no comparision to the asian version.
I actually gave my asian version to a friend.
This watch has become 1 of my top 5 favorites out of about 40 reps I own. I never thought that would happen when I ordered it.
