I appreciate English is not your native language, but please try not to add confusion here, (see my next sentence) ....
It is NOT power LED, it is pause LED, which means it has been paused by operator on a watch that works but it still has a very high lift angle and that in turn makes the amplitude look better. The absence of a Graph line running across the TG screen corroberates this
I agree 100% with
@trailboss99 as to the reason for not wanting to return dud watches, (and not trying to sound like a cock) I do believe I mentioned that earlier)
This is a very serious matter, not only for us buyers, but also for the seller, although quite frankly I don't know why I have concern for him now after reading the posts since last night, especially the same TG readings from April and May !!
His only reply here so far was a damage limitation excercise until I got on board after noticing the lift angle, I didn't spot the relevance of the blu tak until it was pointed out by another member
This was the reason I asked for more TG evidence which we now have, was to see if the OP was an isolated incident ....
Clearly it was not and has now been proven to not be an isolated incident, it has been going on since at least April !!
So in theory it could have been years, without further evidence either way we have no way of knowing.
I think at this stage the evidence is so damning that it is time for me to say that this TD is at best a fool and personally I think he is downright dishonest and has no place on RWI TD list but that is no way my decision to make and should be left to the staff so I will STF up now !!
