Bulova 11 ANACD casing problem

[EpsilonLyrae]

Hello everyone,

I have a problem in casing a Bulova 11 ANACD movement. I attach some pictures of the parts. Since it was an eBay find, there's some possibility that something was really messed up.

When cased, the movement (with its ring), slips down toward the crystal. It's tilted in a way that makes difficult to operate the crown. Movement, movement ring, dial seems a perfect match but they fall down with no support from dial side...

I have:

1. the white movement ring (seems to be a perfect fit for the movement, maybe not for the case?)
2. Acrylic glass, diam. 31.6 with an inner chromed ring. The ring is totally loose in respect to the glass, meaning that you can remove the ring by simply flipping the crystal and it slips out. It has outer diam. about 29,7 mm, inner about 28mm. I think it's not the original one!
3. Case, diam. 38 mm, opening about 29,3mm. about 31,44mm for the crystal recess. Inner back says model 7313.
4. Dial diam. 28,5mm

I've found an original crystal for case model 7313-4, maybe in the original Bulova the dial rest on the crystal ring? Is this the correct casing for that kind of Bulova's?

Can the problem be solved by using the correct crystal with tension ring? If so, which Sternkreuz model should I buy: standard ring, wide ring, recessed ring?

Thank you very much,

Regards.

Is the black ring below the movement ring the dial rest? Is the gasket installed before screwing down the case back? Do you have a photo of the movement and movement ring in the case?

Hello,

no idea of black ring usage, tried to fit it as dial rest but no way, I'll try again in the next days and send pictures of movement in the case.

Thanks!

It looks like the typical dial rest for Bulova's 11AN* movements. And Bulova's used a dial rest for flat dials like yours on the 11AN* movements, so one will be needed to have the movement sit correctly in the case. They do have an orientation so try flipping it over and fitting it that way.

Thank you very much! 

The correct position should be between the dial and the crystal ring?

Thanks again!

It goes on the movement just before you put on the dial. Here is a photo showing the black dial spacer on the movement. Make sure it isn't covering the holes where the dial feet will go when you put the dial on.
