Hello to all

UTO-RON or not UTO-RON, that's the question

I would like to begin a survey to the series number of this variation.
It concerns only about 1133 g with grey sub dial. there are 2 variations, both with deeper sub dial.

The earlier variation has the same printing like those known as "transitional" blue metallically Monaco.
Here is "UTO" and "RON" aligned directly below in the text " AUTOMATC CHRONOGRAPH" , as to be seen in the early prospect with blue lumen hands.

The second variation of grey sub dial Monacos has a printing same as in later series with black sub dial. Here "UTO-RON" is not aligned any more .

The serial numbers would interest me and in the end the number of watches still represent both variations.

I think may be a late 157xxx and 158xxx .....................

I am happy about every mail, I will tell about the result, if requested, to the participants

cheers
Mich
