I'm very close to Respo analyze on this matter.
I prefer the 976 to the 986, because I don't blike the date window and the larger dimensions of the 986, which looks more " square " than the 976, but to each his own...
In your list, I prefer the Grande Date to the Grande GMT, even if the Grande GMT is a very cool watch.
Here again, I prtefer the simplicity of the Grande Date, and to be able to see an 8 days movement through the sapphire case back is cool.
The movement has a decent finish.
I would pay attention to the Grande Date, to answer you...
Best,
Nicolas
