The 5146P is on the rarer side of this reference, it’s pert of the most prestigious house of horology, it’s a complication that was invented by Patek, an eternal classic.
The LF is a nice watch, but it’s future is questionable( numerous financial issues), the movement is nicely finished no doubt but it’s outsourced, so it’s not comparable with the Patek.
Yes, now the LF is the latest greatest thing, but I don’t feel this will hold on the long term...
To me the LF, it’s a new nice brand, but I find it a bit of a one trick pony...
Nevertheless, if the 5146P doesn’t sing to you anymore, it’s natural to let it go and get what you will enjoy!
After all it’s about the sentiments...
