If I am not misinformed the two have different references because;
Ref 265.81.20 have classic silver/grey dial
While the;
Ref 265.8.08 have the same dial design but “ice blue” (light blue/purple) colour area inside the minutes marks.
But I might be wrong – I am not that into the ladies refs…

Here is a pic I found on the net showing the “ice blue” inner area.
