I have been excited to finally get my hands on one of these. I just ordered RG with green dial. It will be getting plated by flan

Yes, the screws I received are of very high quality and strong. You will be impressed at how accurate and precise the machining is as soon as you put them in.
Again, bizarre that this is where APSF decided to shit the bed on these.
Awesome, I can't wait. I also have a Deep crystal coming today, which I'll have to compare against Prof.
just seen this sorry for not replying. Actually im in two minds whether to keep the chrono or the 400 but not both......
I do tend to prefer the clean lines of the 400. So I'm not going to remove the bracelets just yet incase I do something stupid and mark one of the cases before I sell. But I've measured with calipers and the distance between the plots and edges seems very close, I'd be surprised if they don't match although one thing I did notice was.....
the thickness of both bracelets does actually match closely the curved edges on the side of the cases. So putting the 400 bracelet onto the 26240 might mean it would be a little thicker and noticeable, and visa versa the thinner bracelet would be slimmer. That may change where the plots fit within the centre of the bracelet.... hope that makes sense. I'm sure someone in the previous 166 pages must have tried to swap them over?

It does and that will exactly be the case since on both bracelets the holes are centered, therefor the thinner bracelet will sit centered in the thicker lugs.

Eh. Slightly better but nothing to scream about. I think Deep is hard to capture in photos and without videos. I assume top is APSF ans bottom is Deep.

The difference isnt as astounding as Clean vs Deep for sure
So, this is a no go. The bracelets are different thicknesses. I believe the links themselves can be swapped between braclets, however the difference in thickness, flushness and fitment of the bracelet would be affected.
I swapped my crystal on the ASPF 15500 so decided to do some measuring and testing fitting. Images are medium sized to prevent littering peoples' screens too much (sorry). Click for higher resolution if it matters to you. Also, I used ugly lighting (direct multiple LED, single direction) to highlight any flaws, dust, details. Sorry.
26400 LEFT -- 15500 RIGHT
You can see the differences in bracelets between the 26400 and 15500 are differences in thickness.
As for plots, they seem same/similar.
Here are the measurements.

15500 Next
Next up, bracelet swap-a-rama!

Issues with 15500 bracelet on 26400 - plots aren't flush. Otherwise fits and wearable.
15500 fitment
Issues with 15500 with 26240 bracelet. Cannot be mounted properly without redrilling 26240 plots.
15500 with 26240 fitment
Closer examination of the plot holes show they are different. Even the milling is different (At least for APSF. Unsure about GEN or other factories).
As for my little crystal swap, here's a comparison.

Anyway, I hope this was helpful to those interested / helpful to the community in some way. Prof tax for AR goodness, just in case!

Well my obsession with this line is expanding with another purchase RG with RG sub dials
While I have the RG blue dial this is beautiful and a keeper

The sweeping chronograph minute hand issue on the APS Factory AP 26240ST, which also happens on the genuine AP Calibre 4401. Here's the detailed breakdown:
On some APS 26240STs, the chronograph minute hand appears to:
This is actually by design in both the replica and the gen AP Calibre 4401:
The "Sweeping Chronograph Minutes Hand" Issue – Explained
What is the Issue?
On some APS 26240STs, the chronograph minute hand appears to:- Move gradually (sweep or creep) as the seconds hand runs,
- Instead of jumping precisely at each full minute mark like a traditional chronograph.
Why This Happens (Even on the Gen)
This is actually by design in both the replica and the gen AP Calibre 4401:- The Calibre 4401 is an integrated flyback chronograph with a drag gear on the minutes wheel.
- Instead of a "snapping" minute counter like a 7750, it uses continuous transmission, so the minute counter creeps slowly forward during each minute.
- This reduces shock and improves longevity, especially in flyback use.
AP themselves confirmed that this "sweeping" minute counter is a feature, not a defect.
In the APS Clone:
- APS accurately replicated this same creeping minute hand behavior, which is rare in replicas.
- Some users see it as “glitchy” or “wrong” because they’re used to Valjoux 7750-style snapping minutes.
Summary
| Behavior | Happens on Gen? | Happens on APS Rep? | Explanation |
|---|---|---|---|
| Chrono minutes creep forward gradually | Yes | Yes | Design of AP Cal. 4401 |
| Chrono minute jumps exactly on 60 seconds |  No | No | Not how 4401 works |
Happy with the watch, but must say for me the bracelet is to thin compared for the fat mama watch. But thats not a replica issue and only a personal favor.
Actually in the gen, the issue is slightly different.
What happens is that the brake for the hand @9 doesn’t have enough force to hold it in place while the rest of the gears turn, and it does not run continually, but usually gets displaced by 0.5-1”, and it stops there. It does not continue to move after that positional displacement somehow. It can of course be reset but eventually it’ll get displaced again.
AP has been silently fixing this issue for the 4401 and 4404 calibers but you can of course find instances of this issue posted by owners on various websites and forums. The 2024 onward watches mostly have this issue addressed and resolved.

Screws look better. Creeping hour chrono hand too, lolNew batch of purple, any improvements you can spot?
