A7750 28k movement with timing regulator?

[surpur]

I just got an email from Angus about his better pictures on his website. It features a Royal Oak watch with an A7750 movement that is advertised as 28,8kbph. Now on the picture the movement has a timing regulator on the balance wheel like the 21,600bph movements have.

I have so far not seen a 28,8kbph movement that has this regulator. Has this changed or is this a mistake in advertising?

Here is the picture link:

I think the latest batch of 28800bph A7750ies have the regulator.

I just bought two Panerai Luminor Flyback, which had the regulator. Have also seen pictures of new TAG Heuer Carreras which seems to be high-beat nd with the regulator. A nice touch. Not really sure whether the regulator is functional or just for show.

Thanks - that is good to know! I was always wondering why they went away from the regulator since it made the A7750 easy to spot, especially through glass bottoms. On the old 21.6k movements the regulator worked, so I would think this one will work also.

BTW - you can also see on the escape wheel that this is a high beat movement, should have noticed that earlier.

Didn't know that. How does the hi beat escape wheel differ from the low beat?
