Hindenburg Zeppelin LZ129 7046-4 movement removal

[GaryMc]

Hello, I do basic DIY maintenance on my modest collection of watches and would greatly appreciate any help available in relation to an issue I have in removing a faulty movement.

The movement is a Ronda 515 and the watch is a Hindenburg Zeppelin LZ129 7046-4.

The case for this watch appears to be a single block of stainless steel into which the movement has been inserted. I cannot find a way to remove the dial face in order to detach the hands and replace the movement.

In the attached image, the 4 screw holes around the edge are for the cover screws. There are 2 further screws at 12 and 6 inside the case, which I have removed, but whose function I cannot determine. There are 2 small steel stubs next to this screw holes.

The only way that I can see that the dial is inserted is that the assembly behind the cover also screws out, but there is nowhere to obtain grip to apply anti-clockwise pressure, and even under a magnifying class, I can't see that the interior assembly is separate from the outer case.

Thanks in advance.

Hi Gary. Can you post some pictures of the front of the watch and the side view both sides. There is the distinct possibility that it comes out through the front once the bezel and crystal are removed thats if the bezel is snap on, that’s why pictures are use full. Cheers.

Thanks for reply. See attached. I had considered that, but there is no be bezel and the crystal seems to be fixed in the stainless steel.

I found a video this watch, as well as a good review video of an automatic version that appears to use the same case. It looks like a crystal lift would allow you to remove the acrylic crystal and get to the dial.

 

 

I was attempting to repair a friends quartz fashion watch with a dead movement and came across this same issue, except the crystal was flat mineral glass and fitted so snug there was no chance of getting the lift on it. It was truly a throwaway item.

I think you're correct. Its a hesalite crystel with slight bevel. so that must be how the dial comes out. I've give that a go. Many thanks.

Hi Gary looking at the pictures the dial is bigger than the back there for it comes out through the front, as mentioned a crystal lift should do the job.  All the best
