My 15300 was a white dial steel bracelet.
I only have a few photos, all on bracelet. The one I preferred on strap was the 39mm Royal Oak Chrono.
Here was the 15300 with a 217:

This was my favorite model to play with. I wore it mostly on OEM rubber, but here is the Tour Auto. I later custom ordered the same strap with red stitching, and presented the "ROC Racer".
I have enjoyed many custom AP setups over the years (some have I never posted for specific reasons). Aside from a steel tang buckle on my 25770 kevlar strap, I have never used any aftermarket parts. Your 15300 plots look to fit just fine in the photos.
