Personally, I like the Parmigiani, then the Patek, and the Chopard as per your question. If I could make one change, I would go with the salmon dial Chopard over this one - but I realize you're trying to keep to a platinum theme and the salmon dial Chopard is a steel cased one. But I like the dial guilloche work of the salmon dial Chopard over this platinum Chopard. In this case, I would then be Chopard/Parmigiani tied (possibly a slight edge to the Parmigiani), then the Patek Philippe last.
