This one has me pretty excited. 1927 Pat. Date 14K Green Gold Filled single hinge case with movement and case dated 1928. Really clean overall with a replaced crystal; and if the face hasn't been redone it's in amazing condition. When I hit it with a high intensity light, it glowed for about 30 seconds.
1928 President. I find one ad in thr Db calling out the option of green gold. Missing the dust cover. Running and keeping time as received. Mismatched seconds hand noted.
