Carlinwasright has your answer!

Another example: The Nikon F 50mm /1.4 AF-D has 7 lenses in 6 groups. Thats 10 lenses less than the Nikon Z. BUT: Even in old times the step from 1.4 to 1.2 was relativily huge, the 1.4 weighs around 260g, the 1.2 around 380g…thats nearly a 50% increase

The modern prime lenses for digital have - in the lab! - much better optical qualities than the old primes like Leica or Zeiss that are around for literly decades. If anybody can see this differences in real life is a complete different discussion.

Yes! Wear it if you happy with it. But be a little bit careful, these old watches probably are not water resistant (anymore) and so it could get damaged if you wear it in the rain. Maybe a service should be considered.

There are better ways for high risk „investment“ (in other places itˋs called gambling)……if I wanˋt to have a high risk of loosing my money with little chance of winning the bank I go to a high class casino (with my watch on my wrist btw), drink champagne and play roulette. I am sure that there are really good ways to use NFTs, but not for watches or art.

Maybe a nice Nomos or Mühle Glashütte.

If this is not for you then I personally would go for Grand Seiko. Omega and Rolex and Tudor and … are great watches but for my taste much to „common“ - if watches with this price tag could described as common at all.

How about a Mühle Panova?

At first I would not think so much about it: If you want to wear it you should do it! Fashion rules are there to know them and to - sometimes - break them if they don‘t suit you.

If you wan‘t to meet in the middle: why not a bracelet out of white gold?
