There is no right or wrong but rather beauty is in the eyes of the beholder. What fits right for me does not necessary apply to others.
My view is that you pay for what you get. 5k euro or less you probably have to settle for ETA or modified ETA movement watch. That is the reality in the industry and across all watch brands. It really boils down to what you like and how big the hole you want go burn in your pocket. I started with owning ETA movement like the IWC pilot Chrono and other brands like Omega, Tag and slowly move to modified ETA based watch like UN, etc and as I understand appreciate more about watches and for long term values, I only buy in-house movement watches now like the JLC, Panaerai and of course IWC (latest collection is the PPC).
If I won't say I am buying a watch but rather a timepiece. To me a watch is a device meant to keep time accurately and reliably and thus if you need a watch go buy a guartz. For a timepiece is is an art and brings along with it it's unique history and tradition which cannot be replicated coupled with the technology that takes years to develop. This forms the character of the timepiece and this is what I look for when buying one.
So for me the I look at first the complication which must be in-house movement, the design of the timepiece and finally if I can afford it and if not start to plan to save for it or rather not buy anything. In house movement is what defines the life of the timepiece and that of its creator. In house movement brings along good resale investment value as well even more if it is limited edition.
The above are just my person views and thoughts.
Thanks and regards
