Seen a similar Art Deco dial (& cleaning tips)?

Wondering if any art deco lovers have encountered a similar dial design? Photos would be great.

Needs some TLC.. any light cleaning tips while we're here? Parts look stained but wouldn't mind getting some of the dirt off if possible with a non-invasive method.



P.S. It's got an ETA 717 engine (though not running at the moment)

Any cleaning you do is a risk. I would start by using a blower to remove any loose dirt. Then careful removal of dirt using cleaning sticks would be the only other thing I would do, making sure to stay away from the red areas (they look like lume?).
