I loved them all on they’re own merits but I somehow found that the 40-41mm was a little to big for me as a dress watch , also I value a nice reliable manual movement that can be serviced by any competent watchmaker and doesn’t need to go back to the manufacturer.
Off course all are solid brands , and I don’t think they will ever disappear but the Vacheron is built with easy serviceability in mind .
As Kari Voutilainen reviewed the cal . 4400 , and declare it one of the best modern manual movements. To me that’s good enough.
I also think that 38mm is a more timeless size , but off course it’s up to you to decide what songs to you the most .
I believe that they should be tried on and seen in the metal .
Most collectors don’t care about the movements, but some Journe‘s tend to be finicky, the Lange it’s not temperature adjusted so it has slight deviation, not much , but it does , and I never had a Ferrier so no comment on that . I liked the dial of the CS the most , until I analyzed the VC in detail and it surprised me. The VC is more restrained then the others , it doesn’t have that WOW factor and it’s not overhyped . It’s the watch for the person who likes to spend time with the loupe in hand and explore the little details , so that’s my choice.
Hope I helped ,
Zsolt.
