I really like all three watches equally and for different reasons...
The 1815 in RG was the first and I think it has one of the nicest designs ever,
I think with either the TZ or the anniversary you will have a great watch. I chose the TZ
I handled the Anniversary and had the chance to get it and of course for "ideolgical" reason of not getting an Automtiatic I let that go.
That's it for me though.. I hope that that temptation does not come around again... even if it does, i cant afford it anymore
