Don't shoot till you see the white of their hands. LOL
The Rolex BC in the 6538 and 5510 in the 57 – 59 range enjoy these great big white lollipops seconds hand. They are a very distinct look. It was not a standard issue and as with Rolex no particular information other than the obvious visibility that the white seconds hand provides on a dive watch. It was by no means a standard issue.
The other no crown guard 6536/1 and the 5508 have also enjoyed the white Lollipop seconds hand but it is substantially smaller, obviously, to fit a smaller case.
Below are a couple of pictures to enjoy. Please feel free to ad yours and the give more details on the mystery of the white hands.
Enjoy
