The first pick is a 26331 clone with a movement sold as a cloned 2385 and a case thickness of 11.0 mm to 11.3 mm. The case diameter is 41.0 mm. Subdials sit at 3, 6, and 9. The date window sits at 4:30. These numbers match the Audemars Piguet Royal Oak Chronograph 26331.
Factory names change. A listing labeled APS or OMF does not prove the movement. Ask for caliper photos of the caseback and the side profile. Ask for a photo of the movement.

What You Get at Each Price
Prices vary by seller. A cloned 2385 version costs 2 to 4 times a modified A7750 version. A quartz version costs less than both. The movement is the first cost. The case and bracelet finish are the second. Ask for a video of the chronograph start, stop, and reset. The minute counter at 3 should jump once per minute.
