I would go to the DS. It is a beast and I love it. One of the most spectacular movements ever. I would suggest you to elaborate a bit more your questions to get answers. Without some explanations of the context, it is difficult to answer you. Thanks. Fx
You might not be able to get one much longer. The watchmakers who make the DS are now assigned to the 1815 Rattrapante. And as Francois stated, the DS is a magnificent beast.
