Thanks all for your input and compliments. Very much appreciated.
The crack on top of the 90 nearly broke my heart. I couldn't be sure if it was original or service and would be a deal breaker. However, with the watch in one hand and Speedmaster101.com in the other hand, I noticed that the 70 is also a nice little indicator, as in:
Up to 1969: Dot diagonal to the 70
1969 - 1978: Dot next to the 70
1978 - onwards: Dot below 70
As for the lugs, you are right. They seem a bit polished here and there, but whoever did it, knew this and if he did touch it, it wasn't too much.
Tricky to get in a pic... It's where the reflection changes drastically.
