3135 date not working

[Trueblackpercula]

Changed out a main spring and watch is working. Problem is the date does not work when hands pass 12am but the date works when I pull out the crown to the last position. Any suggestions?

Check date jump train( canon pinion to jumper spring).

In case you didn't find the fault, a close- up picture of the train helps.

Assuming a Rolex 3135, watch this video.  It appears to me that there are two different mechanisms to change the date and they are somewhat independent.

What is a jumper spring as I do not see it nor is it mentioned in the video.  Also could it be anything else as the date does work but only when I pull the crown out to the last position. I also do not her nor see anything broken.

Please take a picture of your current dial-side movement and one of the experts on this forum will help you.  With no picture, we are simply guessing.

The jumper spring is the part that keeps the date ring steady, otherwise it wil lbe be moving around all the time.

The date  quick set mechanism is completely indipendent from the one that advances with time. I did not even exist on older maov'ts. So it's normal that one may fail but not the other.

Advance time and observe the motion going from the cannon pinion, to an intermediate wheel, to the date wheel, to the date ring. Where the motion is not transmitted, there is the fault.
