Mainspring slipping, replaced barrel, spring, arbor, still slips

Did you ever compare the bridles H , length thickness and stiffness ?

Yes, I did, and they are not the same. Even so, the feeling of the springs is completely different. The Seiko/Orient springs feel considerably softer and the Swiss springs much stiffer. Seiko/Orient springs easily deform if you don't handle them carefully.

This is another reason, except for the super tiny Diashock springs for the escape wheel and the third wheel, why I avoid Seiko/Orient movements. Anyway, the next time I service a Seiko I'll try Alex's method. He demonstrated it on a balance Diashock spring (not too challenging) but told me in a comment that his method should be working on the other Diashock springs as well. It remains to be investigated.

I avoid them as well, getting parts seems like a lot of trouble.

I can't believe people have so much difficulty getting hold of Seiko Parts.

I know some parts are getting rarer but I've never had any problems.

I think you have to be in the know to know where to go.

Your movement is eta2790 which beats 28800bpm

But you have replaced its mainspring with one for ETA 2750.  which beats 21600/ hr.

Jules borel lists different mainsprings for the two calibs,    do they interchange ?

No they don't interchange but this has nothing to do with the vph and is because one is Manual and the other is Auto.
