Have not done one of these before but sunlight just caught the dial today and made me realise how much I love this watch. Heuer Carrera 2447S 1963 first execution eggshell dial no "T". If you told me I could only have two watches would be this and a Speedmaster. If you told me I could only have one I'd hide the other. Probably in the sock drawer.
Picked it up five weeks ago and haven't taken it off my wrist since then. It's the longest wrist time any watch has ever had with me.
