German "Mercedes" Clock

Picked this up at the local thrift store yesterday and would like to know more about it.
It looks to be small desktop clock on a heavy chunk of marble.
I think the face cover is plastic and not glass.
Says Mercedes on it and made in Germany. Doe that mean the car company made it?
It does have a vintage look and patina to it but I would like someone to take a stab at dating it if possible.
I wonder if it's 40's? It has an art deco look to it.

Faint memory that Mercedes was a trademark of Staub, extant in the DDR from the late 1940s until around the 1980s/90s.

I'm sorry, what does the above statement say about this clock then? I'm not familiar with Staub. Thanks.

In short: The movement is East German, probably 1950s-70s, made by a fairly obscure - but quite prolific - company called Staub trading under the name 'Mercedes'... but definitely nothing to do with the car maker.

And the frame the movement sits in was almost certainly produced and retailed by another company altogether who just bought in the movement.

Ah I see. thanks so much for the info!

I think the body is polished slate rather than marble.
Clocks like this were still quite common on boot fairs in the UK in the late 80s and 90s.
I used to find them in polished and unpolished finish.

welcome scavo, good to see a new member hit the ground running

In fact, I've just remembered that my maternal grandparents had a barometer and thermometer mounted on a cut, unpolished block of slate. It could still be kicking around in the family somewhere? Strange thing to remember as it must be 20 years since I last saw it but it had green felt on the base.

There has been a company called Uhrenfabrik Gebrüder Hauser in Weigheim it was active 1923-1998. Gebrüder Hauser used Mercedes as a brand name as well
