It's going to have the same low beat DG2813 variant that all the rep Skydwellers use. There isn't another movement that fits the unique needs of quickset date plus center 24 hour wheel. This is not a bad thing as this variant is generally very reliable and replacements are easily sourced. Like all 2813s, it's really a throwaway movement. Once the backside combined bridge is removed to access the train wheels, it is a nightmare to refit the bridge onto 5 skinny, wobbly pinions that keep falling away from their jewel holes. I have extraordinary patience and after doing it successfully once, I won't ever attempt it again.
This means that extreme care needs to be used when changing hands. The DG2813 second hand pinion is ultra thin at 0.17mm and will snap off if your hand twitches wrong. It's connected to the second wheel which is under the combined bridge on the backside. You get the picture.
This is not meant to steer people away from the rep. As mentioned, the movement is generally reliable. I have 3 of them and 2 have been flawless for years. The other was intentionally sacrificed for exploration.
To say that this movement operates "like the gen" is a bit of an overstatement. The gen does have a quickset date but that adjustment also advances the month indicator so you initially could have to cycle through several or many months to reach the correct month and day. After that, the gen perpetual calendar changes the month indicator automatically and even flips the datewheel twice in 30 day months. A manual adjustment is necessary each February. The gen also uses hour jumping like a GMT while the rep movement does not. This feature allows for time zone changes without changing the 24 hour wheel.
The rep movement does have an independent 24 hour wheel that can be set to a second time zone (like GMT time) and since the month indicator can be manually adjusted, it can fit the bill adequately. The lack of a jumping hour hand makes it a little less convenient for frequent travelers across time zones since changing your local time also changes the 24 hour wheel. Then you would have to change the 24 hour wheel back to your reference time (like GMT time). Adjusting the rep 24 hour wheel to be exactly in sync with the main hands is a fiddly ordeal sometimes taking 10 or 12 tries due to lead and lag play in the gears. Once set, it's best left alone.
I never even notice the low beat but I don't stare at my second hands either.
The variant is called the DG5833
