I will go for the 5059RG.
It is much more 'lasting' than the Langematik Perpetual in its look department.
This lange is a bit too complicated in its layout.
The 5059G has a very classical appeal with its officer case. The con of 5059 is that it is rather thick at 14mm
with its diameter of only 36mm. And it is and will always be a shadow of its better sibbling , PP5050.
I think one of the most beautiful perpetual PP has in its current range will be 5040. It wears beautifully on the wrist
Value wise, Patek will be slightly better than the lange.
In the very least , you know you will at least retain 60% of what you pay for either watch.
Hope it helps.
