Sorry maars, but that's not true. Sounds like you've started doing some homework!.. Where did you see them selling a V2 or V3 with 21,600 A7750? The V2 and V3 both come with 28,800 A7750s (and have always come). The only version to come with the 21,600 A7750 was the V1 with sapphire and I'm not even sure that came with the older 21,600bph engine. Very few watches made after 2007 come with the older 21,600 A7750s.
The "L Swiss made L" is not too close to the markers.. I've held a gen pam286 in my hand next to my 253 and it's spot on. The problem is the dome crystal distorting the photo a bit towards the edges od the dial. The real problem is that the markers on a gen are on a completely separate piece of the dial laid on TOP of the hobnail texture.. So looking at the dial from inside going outwards you see: "hobnail... dial marker ring.... hobnail.. rehaut"
