ETA 2892-A2 big date pdf

[Danh]

Hi all

i bought a watch that has been wrongly put together by someone (good price and worth fixing)

it has a 2892-A2 movement with the big date chronograph module fitted.

the watch was sold as “date not working”, I have stripped it down and got the mechanism working fine - the issue that it came with was the date discs had been put on wrongly which was jamming the change mechanism.

would anyone have a pdf that shows the correct alignment for the discs on assembly

thanks for reading

An update - I believe the module is a Dubois Depraz 4500 (possibly the same as the Breitling B44)

Sorted it - this is the correct set up - the clue was in the first image I posted (lol)

Hi Dan,

Ive got the same mechansim with exactly the same problem. Only in this instance it was me who caused it

Did you manage to find the data sheet for it and if so could you point me in the right direction.

Regards

Johnny

I have images that can help you - if you follow the set up from the images it should work a for example if you match the wheels and then add the wheels at 04 as shown
