I dont have any moore story on this watch, it was found in a flee marked some years ago.
Another number on the watch, I haven't been able to find any story on.
Anyone recognice the numbers or have any idea from where its from?

 

Great looking piece. Are you talking about the number scratched into the caseback movement side? If so, that’s most likely from a watchmaker who serviced it some time throughout its life. Wear in good health.

 

136654. in black is the number I am curios about.

 

,may be the private telephone number of the watchmaker´s wife

 

The number in black is felt-tipped and I wonder were its from?
The engraved number is from the old days, probably the seller of the watch Hans Gaarder back in the days

 

The strange thing is when I called her its was your wife
And she told me you got new glasses, so you need get back home for drinking water

 

As @gatorcpa said, it's likely from a watchmaker. That would be his code for the job.

 

But where can I find out what watchmaker it is?

 

Thanks a lot.
The schratced number NUF281 is the number of the shop in Norway. N.U.F. norsk urmakerforbund (Norwegian watchmaker association) 281 is the shop number from that time.
YES and it took a while to figure it out, very simple if you know it, and very difficult to find out such a simple thing.
Its just how it is with this kind of watch

 

Beautiful Ranchero and what a flea find. Hard to come across rare gems anymore, especially not in that condition.

 

So then, it’s as all the of us said : from a prior watchmaker who serviced the watch

and because nobody has yet : dibs
