So the answer to my question is that it's the combination of the movement number and March 1970 date that suggests it should be a 1039/516?

 

I am far from an expert on this topic and there are many more members on this forum that could answer this question more accurately than me but I do believe that the bracelet that came originally on this watch was the 1039/516. I believe that the first 1171s with trapezoid logo were released the same year and can be found on some 69s later in the year.

Best £100 odd I’ve spent in a while!

 

Have never received an extract with the type of bracelet detailed. Sometime “leather strap”, probably meaningit was not delivered on bracelet.
