Date Window Mod?

[Martyd3]

Had anyone tried to slightly widen a date window using a jewelers file? Just wanted to know if I was looking for trouble trying to do so

Thanks.

As in for a A7750 dial to be used with the 7753 movement? "Slightly" is about 2-3mm. Your DW will be so wide that you will see the teeth of the Date Wheel.

Here is a overlay of a Pam 250 I did with 7753 and A7750 w/ 3,6,9 subdial layout.

The "20" in the DW is the A7750.

I had to do this on my Inge to get the date properly centered:

If you go at it from the back side and angle it just right, it's not bad; touch up with a little black paint and what you see above is the finished result. Granted, I only had to remove a very small, minimal amount...

That is exactly what I need to do. I just need to take a little of of one side of the window to center the date. The particular dial is a Rolex and under a cyclops. I hope it works

I did go at It from the back side and I thought my angle was spot on. Well she still wont talk to me.

Marty- Be careful with that one. Since Rolex dials have a bevel around the date window, and because it's under a cyclops, any room for error goes out the window as those two factors will only pronounce the details.

Try more lube next time. Just when you think you have enough, add more It's critical for those kinds of situations...

oooooh - this is cool info...my 3-6-9 old skool arabic dial Navitimer has its date at 4.5...it comes with a small date window compared to the gen and a real lousy dw font...i picked up an eta 4.5 datewheel and plan to swap the old one out...it still won't be like the gen Navi's dw, but a step closer...it could benefit from a slight window expansion, too...but i do wonder if it might be noticeable on a dial that is smooth/matte versus patterned...but then again, the Navi dial is pretty busy, so it might not be that noticeable...hmmmmm...another potential project...R

Isn't there just a little spring that is responsible for positioning of the date wheel? Can't seem to find a picture of what I mean. To re-center the date wheel could you not adjust the keeper spring? Seems a little less....permanent.....if something should go wrong.

No... It's an actual wheel that is solidly in place, with teeth on the underside driven by a gear... there is no "slightly" moving the position unfortunately.
