I got this one years ago but never knew what Ref it is.
I dont want to open it myself since im not much of a mechanic.
The braclet is a 1171.

 

Should not be that difficult... a Ref. 145.022

 

surely a 145.022, end 70ties early 80ties.
Still has the bezel which was used in the 70ties.
The Q in Qualified has a different font as the earlier casebacks. So somewhere in the 80ties

 

Thanks mac&sulaco!
