Eterna Manual 1941


Eterna manual 1941
Movement no: 3916054
Caliber 520-U
Case no: 3777416

Caliber 520-H I found in the book ETERNA Pioneers in Watchmaking was from 1941
This caliber does have the shock absorber and has caliber 520-U so we can assume it is from 1941.
I also found an advertisement from 1940 in which they promoted the shock absorber on a other manual calibers 1050.

Complete serviced but that is normal but this watch is in great condition
If I have to write down what there is done the list will be big.
I like to look at the movement knowing what is done there!
Like new tyres spring, like new buses between the platine and gap for the spring drum
New original crown, new glass etc.
And of course complete serviced so it has now an amplitude of 300.
If I did write it wrong in English please do forgive me.

But I like to explain what has been done instead of talking about a great new Hirsh croc print strap.
Most sellers do, so you do not look at the movement!
It has the correct screws to hold the movement into the case for example.
I can go on so just let me say a great watch with great heavey luggs, size 34,5 mm ex crown.
