I agree with you, I told my friend to wear the v7 for a day on the wrist. I always look at his watch and try to see whether i notice any flaws on people's wrist.
Sitting at the table for dinner, the easiest tell would be the colour of the cyclops as it is really easy to depict the blue tint.
I recognise all the dw font (modern and classic, for both rep and gen), but it's still hard for me to identify in a distance. Yes, it is easier to tell if I hold his hands and stare at it for a few seconds, but I bet that won't happen in real life if your status matches with your watch.
I also found that the crystal reflection often affects the visibility on the watch, I can barely see whats on the dial clearly when my friend is moving his hand
Low beat movement is nearly impossible to tell in real life situation, you have to stare at people's watch for a while without the owner moving the watch in order to tell whether the watch is 6 or 8 beats per second.
The mega tapisserie pattern on the dial is really hard to judge whether it is rep or gen, since ap has released different types of dial, I wouldn't call people out because the dial is too dry or doesn't look good.
In the last 12 pages, nearly everyone focuses on the flaws of the dial, cyclops, dw, tachy ring. The major flaws that I determine whether the watch is gen or rep in real life is not on the dial itself, since you don't walk up to people and awkwardly stare at people's watch, the things that I see are the bezel screws and the endlinks of the case, these are the two major tells that I can spot from far away.
The bezel screws are well-polished and rounded in the gen, you can easily tell that's a gen from a mid-close distance. Some gen APs aren't that well-polished and perhaps people describe some batches are heavily beaten, but if you have seen the gen divers you know what I mean and it is easy to spot. Sunken screws are not necessary, because the bezel screws itself is already a biggest tell.
I'm surprised nobody here actually talk about the flexible endlinks in here, noob got it right with their divers, but jf and xf were doing it wrong. The gen endlink of the diver is supposed to be flexible to make it fit the wrist better, people with a small wrist when wearing a diver, the strap is like hanging around their wrist and it becomes NO.1 tell, and that's what I would called "you can see it across the room", but of course if you have a 7inch wrist or larger, it becomes harder to tell. The simplest fix is to use a metal surface polish machine to polish the top of the endlinks to make it flexible.
People are often discussing about how the back cover or the movement on the back is a major tell, but I would say if you take off your watch, if that person has owned a gen diver, the flexibility of the strap is easy to tell without looking at the back/movement.
I can at least point out 20 flaws on the diver, but I would still believe the diver deserves to be a super rep, because in real life situation all the flaws are hard to spot even if you know what to spot at the first place. People usually determine whether your watch is genuine or replica usually based on your outfit or how well you carry it.
