This is a German patented alarm clock in the form of a pocket watch, made by the company RSM (Reinhold Schnekenburger, Mühlheim, company founded in 1882).
The first picture shows it side by side with the Omega Tissot my father left to me. The last picture shows the alarm clock in the company's catalog, as well as the RSM rose logo.
Marked on the face with D.R.G.M (Deutsches Reichsgebrauchsmuster, meaning that the design or function of an item was officially registered inside all of the Germany states and not only locally registered as it was the case before the introduction of centralized registration) and D.R.P. (Deutsches Reichspatent, meaning the product is patented).
It also bares the RSM rose logo which dates this to around 1910 and possibly made by Uhrenfabrik Muhlheim Muller & co who continued to use the logo till 1913 from when they took over the bankrupt Schnekenburger business in 1900.
It is in bad shape, the dial is a mess, the nickel plating is oxidized, the clock doesn't work. I'll restore it as soon as this COVID thing ends. It has a 4, 1/2 inches dial.
