The only manufacture marking is that of a small Butterfly inside the alarm dial. A full wind up on the time side would be about 24 hours yet excellent timing, on the alarm side wind-up it will last about 45 seconds and No stop lever (so if you will use the alarm just wind it up about ¼ of the way or maybe ½ a circles). The Alarm Bells are for the function of the Alarm Only. This clock also has a Seconds Dial. All metal parts (no plastics on this one) including the movement was thoroughly clean and oiled. The inside picture shows the metallic color but after cleaning with 00 steel wool we painted in a Gold color. The bottom wooden base has a slot so you can install a brass color name plate etc.. 17 inches tall by 9 inches across and about 4 inches deep. We do not use AI on our clock descriptions, What you read is clear and true, no exaggeration required. Also we will try to take a picture of the inside as the clock is been restored (if I remember lol). Bulova/Franz Hermle Mantle Clock Westminster Sounds, Super Clean!!
