my personal opinion is to stay in Patek "house" .
I am collecting watches since years....started with Daytona vintage....and finishing with ONLY Patek and one Breguet to satisfy my tourbillion needs!
Remember that Pateks are always increasing in the market ....look in Antiquorum world !
By the way .............buy always what you really like and is giving you joy in wearing at your wrist !
All my best
