Anyone know this cockpit clock?

Buddy picked this one up from a friend. Any idea what plane(s) it came from? It's a waltham and it's functioning properly. Guessing it's a radium dial, too.

layout and functions look like my 8-Day Revue Thommen I have on my desk. Set the time with the lower right and start/stop the chrono at the top right. Probably a common layout??
Sorry, no help on dating and provenance
I love mine although it could probably use a cleaning and a service.

We also have several; this one is a Wakmann.

Here is mine. It's a type A13A 8-day,22-size, 22 jewel aircraft clock was made by various makers Waltham and Wittnauer. A little info out of some of my books. On eBay you can get a cool clock stand and use it in your office.

Also it sort of works like a chronograph when you push the top button the sweep hand will go every 60 seconds the counter hand the arrow hand will move to the next minute mark. You hit the button again it resets and stops. The bottom nod for winding and pull it out to set the time. If it doesn't have Swiss on the dial, it's a Waltham. They were used in the 1960's-1970's on B-52 Stratofortress, Fighters F-100 Super Sabre, T-33 Trainers aircraft.
