Older the better for me, just like 1675/5513.
An old original gilt fetch the most money and are most prized, 7206 bracelet, orig caseback, dial, hands a must.
Chapter ring best then non chapter ring same as 5513/1675.
If on a budget then just get the best post mid 60s matte dial one you can find I'd suggest.
No particular matte dial 'mark' commands a premium yet over another, well not in my book anyway.
Hope that helps and the 1016 website,

as pointed out, is a must to learn about all aspects of the piece.
