That and a measure of perfectionism. Together that makes for a great inconvenience in life trust me.
But then I learned to demand less and allow more. Say, for example, I have always wanted to have a black car. But I never bought one because I knew I was going to see a lot of hairlines on the surface no matter how careful I am. Then one day I said to myself, "It is better to have a scratched up black car than not to have one at all."
The same logic applied last year when Omega came out with the re-edition of the Seamaster Ploprof. The original had the date window at three o'clock. The current one has it at between four and five. And I hate that a lot. Give me three or six not this, you know? But I was the first person in my country to decide on the watch still. The slanted date window issue dismissed totally. A little imperfection for the greater good (of having the watch as opposed to not to have it). 
So you see now the round subdial on the 976 is not too hard for me to get over. Hope you find some useful thoughts in my senseless rationalization!
