Here is some info from a recent MWR discussion on the Omega '53.

From James Dowling:
Hi Folks
One of the big differences betweent the Thin & Fat Arrows is the circled T on the FA.
Take a look at the document and particularly the CADRAN (dial) section where it says "Pointes RADIUM"
The hands section at the bottom right also includes RADIUM in its sepecification.
I think that explains why the dials were switched.
Good Luck.

Bingo. Previous assumption had been that the recall more)

had to do a reg requiring the circle-T, but now we see that apparently it had to do with a reg requiring tritium.
Another, more basic mystery surrounding the Fat Arrow: why did it put on all that weight in the first place, and why does it appear on at least two kinds of issue Lemania chronos, as well as the 53? This is one that may never be solved.

My opinion

Hi Bill
My opinion is that the Fat Arrow is the correct design for the arrow, remember that the Thin arrow seems to have been put on the dials in Switzerland.
Looking at the Lemania/Hamilton chronos I have seen; they seem to have had the arrow applied afterwards (ie in the UK).
Other opinions are welcomed.
Good Luck

I had wondered whether the Fat Arrow might have been...

applied in UK on those. I must have a look at my '81 lemania chrono when it's gotten a crystal that will allow viewing of the dial. It has the FA.
