Even when v2's movement look closer to the patek one, It looks like a seagull eta copy and I don't think that it would be a good idea to change an Eta movement for a Seagull copy. Now if it´s a sellita instead of a Seagull I don't know if the date wheels are interchangeable.
I made that exercise here and the first three named were Rolex Omega and Longines, but Rolex is viewed as more far more luxurious, and for the next tag and cartier but, it
So, they basically receive the St -16 ebauches, that probably costs $7, then do some "decoration" to the movement that it's more expensive than $7, then assembly the movements put them in a case that can come from anywhere(?) and inspect them and sell them as a Swiss watch and charge $400 for that, great deal for Jacques Lemans. Well that is marketing at its best.
More jewels, doesn´t imply a better movement.
The CL 888 is a seagull st-16, 21.600 vph, seiko stile bi-directional winding, with sandblasted plates (that would be the swiss part).
And, as FxrAndy says under no circunstance a clone of a swiss movement, the Seagull St-16, Dixmont Guangzhou 2813/4813 and Naning 28/38 are "inspired" on miyota 8205/8215.
