Difficult to call but one way may be to look at where STS start charging more for a service. All the Seamsters back to the Bond in 1993/4 with movement 1120 are tier one, the previous auto Pre-Bond 200m with movement 1111 is in tier 2 so it could be argued that this is a kind of cut off. Not sure whether I would call a 1992 watch vintage though. To be truly vintage, I would suggest an arbitrary cut off of 1970 since this is the last truly pre-quartz era.
