I just received this Speedy Pro 145.022 with mov't no 46XXXXXXX which place it around 1984- 1985. However the bracelet is still using 1171/1 with 633 end link. I've read in Omega-addict article (http://www.omega-addict.com/reviews/bracelets/) that 1171/1 was replaced by 1450 in 1980. When I perused chrono24 listings 1171 bracelet was used in Speedy Pro as far as 1986. However few Speedy Pro as early as 1980 had used 1450 bracelet.
What is the explanation behind this inconsistency? Thanks

 

+1 I agree from the research read on this very issue.

 

OK thanks !!!!

 

It is correct if 84-85

 

Thanks George.........
