I have had that Sorna for many years and kind of forgot about it... Great looking case and stunning dial.
Found it in my drawer today head only and thought it looked great with my new rubber band.
Then I came up with the idea of setting up the 12/24 display as a GMT hand

Just take the hand off and set it to my reference time zone, Paris +7hrs from Central Time in my case.
It all worked out well, until I found the watch to be really looking good and thinking I should set it to GMT instead for easier global time reference.
Took it apart again to reset the "GMT" hand and while pushing it into place I broke the stem

I think I wedged it against the mouvement holder.
Did I make a mistake by keeping the stem in when working on a caliber? Any recommendation for future reference

I dont know what are my chances to find a replacement stem for it....
That would have been a nice looking watch
