Patek 5146 vs 5327

[kungpow]

I normally don't post much, but a relative recently asked me about a few different Patek models, and so I wanted to ask you guys for your thoughts. Here are the 3 models he's considering:

5146/1G-001 (bracelet model)
5146R-001
5327G-001

So I know it's hard to predict what will happen in the future, but he's wanting to know which one would be more collectible (holds better value, harder to find) in the future if he wants to pass it down to one of his kids/grandkids. He'll probably wear the watch only occasionally.

I don't know much about Pateks, but my initial thought is that the 5146 (any metal) has been around for a long time and will be easy to find in the future. The 5327 is a new model, has a beautiful blue dial, but not sure if its production is limited. I also realize the 5327 is double the price of the 5146.

Any thoughts about these models?


Thanks,
Brian
