width of tension crystal

[avantbiy]

In the past I have used the sternkreuz  ATC and ATG tension crystals on vintage watches with success. I do however have a watch requiring a new tension crystal where it also covers the edge of the dial to give it support to stop it being pushed through.

The standard ATC crystal does not have a wide enough tension ring to cover the edge of the dial in this instance. I noticed that sternkreuz also produce ATCB crystals which they describe as having a wide ring. I couldn't find anything in the G22 sternkreuz catalogue that states what the width of the ring and edge of glass was.  From my quick measurements the ATC crystal and ring combined width is 1.26mm.

Does anyone have an idea of the width of the ATCB crystals or have any other suggestions?

many Thanks

I had the same problem so I bought both. So for the record the ATCB measures 2.25mm compared to your 1.26mm.
