But this topic has been discussed many times before so have a look at past posts also...............
1. How much wrist time????? I have an illness which means It is impossible for me to wear a watch for more than a couple of days. I start to get irritable and so change my watch at least once every 2 days...... Here is a scan of some complications from my collection......
So I guess I would wear either a 5970,5070 or 5960 at least 3/4 days each month.........
2. I keep my 5970p wound but only change the time on my 5970Rg.... The 5070 is no trouble at all . The 5960p gets the most wrist time and is kept wound up also.
3. The time I spend with my watches is a pleasure not an effort and yes it is worth every second as long as it does not take me away from my work or family....
4. When I travel I take a couple of watches or else I go insane
A watch for swimming in and one for nightime....
5. I enjoy all aspects of my watches and yes the case back is a big part of the enjoyment.....

Again it is a very individual thing but I would go 5970 5070 then 5960p......In that order...... Don't worry about winding or changing them as this is all part of the different watches charm and character.....
Hope this helps with some of your fears............
What ever the choice one thing for sure.....You can't go wrong with Patek Philippe.......
