Hey there, just wanted to share, because why not.

I happened to find a pretty good price on a genuine black dial for the 15300, so I bought it. It has been used, as the markers were not free of small blemishes.

So then, I bought the 15300 from BP Factory. It's the only one out there, but they did a great job on the date font, which I'm pretty picky about. However, you must get the white dial version when doing a franken as all genuine 15300s have a white date disc. BP factory, for whatever reason, made colored date discs with white ink (blue/black background), which is not gen-like.

Really, that is all you would need to make a decent franken. I sent the watch off to legend to thin and install, and he not only delivered perfect results but has excellent communication as well. I also asked him to clean up the scuffs/scratches on the markers of the dial with rodico or something. I think he did - legend if you're reading this, were you able to do that? If so, how do you do it out of curiosity?

Original thickness: 10.95mm
After thinning: 10.12mm

I could have got it to gen thickness (9.4mm), but it would sacrifice not only the movement deco plate (which isn't a huge deal), but also the deco rotor. Losing the rotor would really be no fun for me, so I elected to keep it all and get it as thin as possible. I asked if I could keep the rotor and ditch the deco plate, but legend said they travel as a team unfortunately. After wearing it now, it's quite nice, but I do think it would fit better at 9.4mm. I mayyyy do the thinning service again, but who knows. At 10.1mm though it's fantastic and a MUCH better fit than before.

After all installation, the dial fits and the date wheel really looks great with all of the serifs.

Overall satisfaction with mod:

It is fantastic. Even with a DSLR full frame camera with macro lens, it is VERY difficult to capture the depth, reflectivity and subtle light play that the dial gives upon viewing. It's absolutely fantastic and truly does take the watch to a different level. However, my gripe with the design itself is that a flat stainless marker at 12 (the AP logo) on a black background of the dial lends to no separation and it's difficult to see when looking at the watch directly. Even harder to capture with a camera. I was having to slightly angle the watch or move something in the reflectiveness of the AP logo so that it could be seen. Not a huge fan of that.

Future mods? Maybe. In order they would be:

1. Prof crystal 2xAR. I know it's not gen like but man it would be beautiful
2. Further thinning. I would sacrifice movement beauty on the backside, but I may do it.
3. Genuine date disc, if available.

Great little build! I reckon go for it and scrap the rotor and deco plate. You dont look at the back of the watch but you’ll definitely feel the difference constantly from the extra thinning. Plus unless you keep your watches on a winder or wear them every day, you need to wind them when you put them on anyway. Is it possible to source a spare case back to do the extra thin version on? Can always go back to with rotor then.

I always liked the 15300 as a gen. I did not know they made the 15300 with black dials.... You are right: the BP DW font is pretty good. How is the bracelet and case quality? Legend did a nice job with this one as well. Looking forward to future builds from you maj. You are on a roll with the smaller, more elegant RO Frankens.

Hey buddy, appreciate the kind words and sentiments. You are a pillar and great influence on this community. I'm not a fan of the bigger ROOs, but have grown to really love the microtapisserie from AP. It's really amazing.

How would you recommend I approach the thinning? What would you do? 9.4mm with no deco or my current 10.1 with deco rotor/plate?

Also regarding the bracelet and case - its just okay. The JF I had was better, but I will say it's better than the DC Quartz though for sure. I think it's gen-like in the thickness of the bracelet, but man it is thick. I almost want to put a 15202 bracelet on it because it would wear thinner.

Where I need to be.
majwilliams0308 thank you for the kind mention. Thank you also to slaughterer62 for the kind comment.

The dial marks were "cleaned up" with a mixture of solvent and also buffing. If I do remember correctly, there are some slight residual marks on the dial, but they remain non-obtrusive to the eye.
I will like to add also that this project has helped me appreciate the smaller tapisseries dial compared with the modern Royal Oaks. The end result is a beauty, you have chosen the dial/hands well!

Hi, I have two questions:

1) does an original 15300 dial fit on a BP case without any mods?

2) are the BP hands slightly shorter than original ones?

What would be today the perfect mix with the clone movement?

If no 15300 reps availiable

Maybe something like that
Zf 15202 case(wich is thick and can pass as 15300)

Gen dial-hands-dw

Apsf 3120 movement
