3135 / 3185 power reserve test under way!

[PeterT]

Hi, with the Christmas hols well under way I thought I would see which of these 4 watches would run for the longest after the same number of winds.
My question is what constitutes a wind? The crown guards do get in the way of a bit of finger and thumb action. Is one wind 360 degrees or what you can realistically achieve using your thumb and first finger?
Anyway, each watch got the same 50 winds. There was probably 10 minutes between the first one running and the last. I should really have pushed in the crowns together but maybe I will do this if I have another go some time!!

The contenders and the order that I got them running:

V serial SD

V serial TT Blue Sub (16613)

F serial GMT II Black

Z serial GMT II Red Black

There should be no difference in the wear rating as the older watches are as new really. None have ever been back to Rolex for any attention. They are all in the same watch box, each sitting on a little cushion with the face pointing upwards.

So which watch will win and why?
