·I think yes. A 2915-1 will always achieve a higher price than a -2 in similar condition. That number makes all the difference, it’s just the way collectors think.
Maybe not all collectors are the same.
There are -1 with characteristics of the -2 and vice versa (e.g. here the movement serial # was more common for a -1).
When it comes to early 2915s, I believe it's not only condition, but mainly originality and completeness that counts.
The OP's watch was basically genuine including the rare bezel and in fair condition. I thought it might go for around 200k.
I don't think the case reference alone made that difference.
And looking at the general auction results, something else must have gone wrong there.
