I recently acquired this little EMKOZA watch and would love to get some more information on it. I could not find much about this brand: EMKOZA should stand for M. Koster and Sons Amsterdam, but that's pretty much it. Seems to me like a nurses watch: there is a red cross on it of course, and the dial is upside-down.
The (plexi)glass was scratched badly but i managed to polish it pretty well. The case and dial seem in good shape. The dial has a nice sunburst which was hard to capture on the pictures.
It keeps surprisingly good time and the movement seems to be in a decent state.
I you know anything about the brand / movement or something else please let me know!
