Thanks. Actually, I have tried using your procedure, it works very well with 
the watch by extending the color range.

The selection seems cover the whole image, if there are other area with 
similar color but no due to lens defect will it be affected too?

Thanks for the hints again, just tried with the taxi image and it works 
well.

Agreed

And it does not take a long time either, I'm doing it a lots for the faded 
negatives since many of them has both sides (top and bottom) faded and the 
center is ok. With not very precise work, it takes around 3-5 minutes each. 
But for exhibition print I can imagine the processing time will be much 
longer.
