Just taken apart a Rolex 6480 with the calibre 1210 movement. I was quite surprised when I opened the watch, as I looks to me like it was in a fire and has some temperature damage. I'd say not more than 140 - 150C, but still quite a bit!
I would be interested how others interpret the pictures. Please follow the link and let me know what you think.
