Which Aquanaut? 5167a, 5167r, 5164a

[rolexboy66]

I’ve been thinking to add a Patek aquanaut to my collection from grey mkt have been thinking abt these 3 watches. Which would you recommend? I currently own a Rolex Pepsi, Daytona panda and a RG Oysterflex. I was initially planning to trade in my 126515ln RG Oysterflex for the 5167r.

Or shd I stick with a SS like 5167a or 5164a coz SS are more popular? Betw these 2 I prefer the 5164a coz it’s thicker.

Thanks all for your comments and advice!
