I just bought an Eterna automatic with movement 1159 that is missing the bumper springs and I think the part that holds them as well. I've never seen this movement before so it is hard for me to tell what is not there but there are no bumper springs, and when I ordered them from Borel what I received was two small V-shaped springs (rather than usual coils). I cannot see how or where they attach to the rotor mount. Anyone familiar with this movement? Thanks.

You'd get a better response to this if it was moved to the wirst watch forum.... unless Eterna made an automatic pocket watch.

Just FYI: Eterna did make an automatic pocket watch. It was sold as a "golfer's" model and was a normal automatic wristwatch movment cased as a small pocket watch. They sold many slight variations of this over the years.

Best,

I was looking for some of these automatic pockets with this movement before I posted. Everything I found online was their automatic WWs.
Do you have more info and or pics? I would like to see one for educational purposes. Also, when were these made?

Hi David,

sorry, still no pic oft the Eterna 1159 in my archive. But it has not the two bumper springs as most movements of this kind. Instead two bumper pistons (right word?) are guided in the bridge with a spring between both.

If these three parts are missing, it should be no problem for an average watchmaker to turn the pistons on the lathe, and to find a spring with the right diameter - no need for high precision.
