GMT aluminum bezel insert (back) color?
When did the color of the back of the insert change from red to blue? Year or model ref.
Did this mark a change in the production process? Why did it happen? Sent from my iPhone using Tapatalk |

The rough guess is early in the 16750 range but no hard time.

The blue-back inserts arrived during the early 1980s.

So, red for 1675 and blue for 16750 in the early 1980s?

If this helps My 16750 with serial 8.58 mln came with a red back - so around 1984 ish ( depending on what date chart you use)
