I picked this one up from the NAWCC meeting this past weekend. It hasn't been serviced yet, so the movt does look dirty.
The bonus for me in this case is the original bracelet, which I rarely find in this kind of condition. Most, in fact all of the 13AT's I have ever come across are in the Jump hour or direct read "White Prince" types of watches.
I am more inclined to say subject watch is an Oakley and case differences are the drawing and case wear on watch. It appears to me that in the Oakley ad, the slight step can be seen in the lower right side of drawing. I think the perspective is a little off in the artist rendition.
Another possibility is that what we are seeing here is a Kirkwood case housing a swapped movement and face from an Oakley.
Case best matches drawing in Kirkwood ad, face best matches Oakley ad. Hand don't match either ad.The absence of a seconds subdial in the Kirkwood ad is a potential ID issue for me.
My vote is Oakley, noting the movement might be a replacement (15/17 J discrepancy)
