It’s the small wheel below. Make sure you have it in the correct orientation. The small teeth need to be facing down.
You’ll need to get a new part bud. That’s your problem.
Also cover that arm and jewel back up. A little
bunk and that thing will go flying!!
So I guess all I really want to know from anyone who's pulled apart a 3135 ZF movement before or if on the odd chance that anyone has images of their rep movement apart, do you have the post built into the date finger like it is supposed to be or is there some kind of removable pin on these Reps????
Would love your advice as well KJ2020 and oascom
There was once one there before. It clearly broke off. It may have broken off the last time you flipped the date. There is no other way for the date to flip other than the quick change.
All the ones I have serviced, and yours is a VR3135, have the post there.
A gen date finger should work but really it could be fixed much more cheaply. All it needs is a little metal post friction fit in the hole - that's all it was to begin with. Since you are thinking about a replacement part anyway, it wouldn't hurt to try to implement a homemade solution. A piece of aluminum wire or a paper clip for example are potential sources of material. You would need a pin vice to hold the paper clip piece while shaping and shortening it. A pin vice is cheap and quite useful in watchmaking. Tiny pieces can be easily shaped with a pin vice and a dremel. They can also be hand sanded with flat paper on a bench. Make the post approximately the right height and a little thicker than the hole. Then taper one end slightly so you can tap it into the hole and it will hold. Just wrap a thin strip of 600 grit paper around the pin and twirl the pin vice around to decrease diameter for both the exposed section and then a little more for the tapered section. You can leave it la little long then sand it down to proper height after its embedded. It can even be taller than the original by 1mm or so. It won't hurt if it's diameter is increased slightly when tapping it in with a jeweler's hammer.
Example of detail sanding with a dremel
Alternately, you can scavenge the part from a dead movement.
Seems that I may have a small leak from the actual crystal which upsets me as that's the hardest to fix from what I gather and would require more tools...
Have a look at the video and let me know your thoughts.

Are you sure that’s not air that was behind the bezel? I can’t see water inside the case. I’ll look again later on a larger screen. My waterproof tests look very similar to yours.
Maybe when I first pulled the date wheel out it broke off… that’s the only thing I can think off now.
Will a Gen 3535-623 date finger fit this? Please say yes!
