Thanks for your reply and for your help...to be honnest, i wanted to try the miyota, because i met a unexpected issue with my both dg3804....remove the stem is easy, but when it's time to reinstall it once the movement and dial are in the case, it's always the same thing,...i loose the hand winding function, i mean that in the winding position, i see the hands turn ! That's crazy !
So i removed the dial, hands and date wheel 3 times on both dg and i reseted the keyless perfectly, but nothing changed, but still the same problem.
I never met such a problem with a eta2836 as i removed and reinstalled stems on this movement maybe 200 times, always in the time setting position, and i did the same with the DG.
What's wrong with this dg3804 ?
I currently have my watch ready, i spent hours reshapping the case and pointed crown guard, installed a clark bezel assembly and plexi, refinished 1675 dial is ready, but i am not able to finish this project with this f*****g stem issue !
