I wouldn’t say it’s rare but it’s an uncommon version. There’s a couple of versions of that dial. Zenith didn’t put ref numbers on their watches but did list them in catalogs and ads. I think ? these came out around the time of the Victorious. Zenith bought Martel who had a Victorious model as well.

These are also based on the Martel 25xx movement if I remember correctly
