Vintage Signed Schwob Swiss Brooch retailer Pin Watch with Floral Motif Setting

Vintage Signed Schwob Swiss Brooch Pin Watch with Floral Motif Setting- Swiss watch, , marked Schwob on the face, with hands, and numerals in goldtone. Also has seconds hand, with the seconds marked off by tens. Setting function works properly, and the watch works intermittently, but not all the time, so I am selling it "as is". Floral and leaf design, base metal with somewhat worn gold plating. 3" x 2 1/8". I am not knowledgeable about watches, so am guessing this to be 1930's or earlier. I believe that this is to be positioned so that the wearer can read the time, so the floral head would be "up" rather than the way it is positioned in my pictures retailer.
