I’ve been going back and forth on this for a while and would appreciate hearing from collectors who have owned one or both.
I bought my Aquanaut 5167A from an AD about two years ago. I now have the opportunity to buy a 5811G at retail, but I need to sell one or more watches to make it financially sensible.
The obvious choice is the 5167A because selling it would realize a substantial profit, making the move to the 5811G much easier. On the other hand, the 5167A is such a unique watch—comfortable, versatile, and arguably one of Patek’s best everyday pieces.
For those who’ve been in a similar situation:
Would you sell the 5167A to fund the 5811G?
Did anyone regret selling their Aquanaut?
Do the two watches overlap enough that you wouldn’t miss the 5167A, or do they scratch different itches?
Does the significant realized profit change your thinking, or would you keep the Aquanaut regardless?
I’m not asking which watch is objectively better. I’m more interested in hearing from people who have faced a similar decision and whether they experienced any long-term regret.

I love my Aquanaut 5167A, but I’ve noticed something that’s been bothering me. The clasp seems to press into the underside of my wrist/forearm and leaves a noticeable mark after wearing it for a while. It’s not necessarily tight—in fact, the strap is slightly loose—but it feels like one of the edges or the shape of the clasp concentrates pressure on a specific spot.
I’m curious whether this is a common Aquanaut issue or if it’s just the shape of my wrist. Have any of you experienced the same thing?
If so, did you find a solution? Different strap length, clasp position, micro-adjustment tricks, or simply getting used to it?
Thanks in advance.

This is my current collection: Patek Aquanaut 5167A, Patek 5212A Weekly Calendar, Patek Calatrava 6119R, Laurent Ferrier Sport Auto, and Audemars Piguet Royal Oak 15510ST. The empty slot would ideally be filled by a Patek Nautilus 5811G.
I’ve been trying to think about this from the perspective of long-term collection building rather than market value alone. The 5811G would become the flagship piece and, in my mind, would overlap to some extent with the Royal Oak and the Laurent Ferrier as a luxury integrated-bracelet sports watch. At the same time, selling the Calatrava would leave me without any precious-metal watch and without a classic time-only dress piece.
So I have two questions for the community:
1. If the 5811G enters the collection and one watch has to go, would you sell the Calatrava 6119R or the Royal Oak 15510ST? Why?
My current thinking is:
The Royal Oak is iconic, but the 5811G would likely become my first choice when I want a statement watch.
The 6119R is the least worn watch in the box, but it is also the only precious-metal piece and arguably the purest expression of traditional Patek watchmaking.
2. If you could keep only one dress watch, would you choose the 5212A Weekly Calendar or the 6119R?
The 5212A is more unique, casual, and intellectually interesting with its complication and handwritten numerals. The 6119R feels more timeless and elegant, and perhaps closer to what many people think of when they imagine a Calatrava.
I’m curious what experienced collectors would do if they were building this collection for the next 20–30 years rather than optimizing for resale value.

Which one would you pick? 5212a vs 6119R
