There is also an on-off switch in the back for the light. Numerals are at 3, 6, 9 and 12 o'clock and small triangles are at the other hours. The motor is located behind the center white area. The power cord runs down a small hollow tube to the base.

The clock has been advertised in a 1959 N. Shure Co., Chicago, Ill. catalog as the "Television Starlight." The ad picture is at the right. The text says:
"The perfect T.V. clock! 1/4 in. plate glass dial is illuminated by means of a pin switch. Soft glow complements any room and is excellent for T.V. viewing. Satin gold finish, metal base, 9" high, 8-1/2" wide, 4-1/2 lbs. Retail $16.95/1959 price"
There is a light under each glass cylinder that heats up the liquid inside and convection currents circulate small pieces of silver colored foil that reflect the light to create an outstanding display. A switch in the back turns off the lamps and the motion will stop.
Numerals are at 3, 6, 9 and 12 o'clock and small lines are at the other hours. The motor is located behind the center area. The power cord runs down a small hollow tube to the base. The cast base is made of a lightweight metal--possibly gold anodized aluminum. Size is 8-1/2" wide and across and 8" high. The clock is UL approved.
There are two versions of numerals for this clock. In the second version, the numerals are of a more flattened design.
A label on the back says:
"Model No. 47 Action Starlight.

. This is often referred to as the Mastercrafters "Mystery Clock" because no model name is on the base. For some reason the name Fantasy was on a tag attached to the line cord, which was apparently removed when the clock was put to use. The appearance of hands floating in the air is similar to the Jefferson Golden Hour but the frame is rectangular. Therefore, the glass cannot rotate to advance the time.
This clock operates in a very unusual way. There's a piece of glass in the front and the back. In between is a sheet of transparent plastic. The hands are mounted at the front of the front glass. The plastic sheet pivots at the top of the frame and moves side to side very slowly. It has four pins attached to it near the center. The picture at the right is at the rear of the hand assembly. Two black ratchet arms are used, one at a top pin and one at a bottom pin. They turn freely and both fit in cogs of the large ratchet gear. At the extreme left and right excursion of the plastic sheet, one of the arms advances the large gear, then the other. This turns the minute hand and gears that drive the hour hand. The other two pins that appear to be floating in the picture apparently prevent the arms from rotating too far out of place if the clock is turned over like it might be in shipment. The back glass serves as a cover.
Instructions on the bottom plate say "These three screws not to be loosened. To remove base loosen the four rubber legs. Guarantee is void if seal is broken. To set time--turn minute hand only in clockwise direction."
A Sessions Clock Company synchronous motor is in the base. A worm gear from the motor drives several other gears that turn a wide shaft with an eccentrically mounted wheel. The wheel can be seen near the top of the picture. This wheel is positioned in a U shaped bracket attached to the plastic that is between the front and back glass. The side to side motion is caused by the eccentric wheel.
The numbers 3, 6, 9, and 12 are in the metal frame. Radial lines are at the other hours. The clock is 8-1/2" high (including feet), 8 1/4" wide and 4-1/4" deep. The dial frame is 6-1/4" high, 7-1/4" wide and 3/4" deep. There is no light. The address on this clock is Mastercrafters Clock and Radio Company, 216 N. Clinton Street, Chicago 6, Illinois. Power requirement is A.C., 110V 60 cycle, 2.5 watts. Weight is 3.6 lbs.
