To me, the ultimate 3 vintage Patel collection would have:
1 Ref 3973
I know, I know, it actually sits in the Patek museum, but it's a 2499 with a split seconds complication, can you judge me for wanting it? Hahaha
2. 3448 in Platinum
In my opinion, this watch is perfect. No need for more words! ( I know, there are only two of these, but when there's a possibility, we can dream).
3. The SS 1526 you've Already mentioned!
To make this a little more fun, what would be your perfect modern trio from pp?
Mine would be a 5164a, followed by a 5970p and the ultimate SS grail, a 5004A.
Best regards,
