The case and hands seem to be the usual 2446C (snap-back), from the late 1960's.

The dial looks pretty much like those used in the later 73663 Autavias. I say "pretty much", because I have never seen an Autavia with the enlarged 30-minute recorder (at three o'clock).

so we face the usual questions:

• Is this one put together -- older case and newer dial?
• Is the dial original (limited production, protptype or one-off) or refinished?
