Corvette Clocks, ‘53 thru ‘82. . . . .
Corvette clocks are broken down in categories according to the age of the Corvette.(Click on clock years to see additional information)
Corvette clocks are prone to many problems over the different years. One of the biggest problems is dirt in the mechanical mechanism. When a clock is serviced, it is oiled at the pivot points of the small gears. Dust and dirt are attracted to this oil. The oil gums up and the clock stops. Another problem that occurs is that these hardened steel gears are held in place by two soft brass gear holding plates. Over time the soft brass will wear and the holes in the plates will become elongated. The gears will tip and stop. Hit a bump, they re-align, work for awhile then quit again. Mechanisms can be rebuilt but an alternative is to install a quartz movement. A quartz movement is very accurate and will give maintenance free service for many years. Another problem with the mechanical movements is that the winding mechanism is a small electrical coil and points system. If the vehicle battery is allowed to run down, which happens with classic Corvettes in storage, there is not enough voltage to arc open the points. In this case the points will stick shut and burn out the coil.
Various Clock Models:
1953/1955: Manufacturer - Westclox - Clocks were powered by the 6 volt electrical system until mid-year 1955. When the 265 cu. inch V-8 come out , a 12 volt electrical system was installed in the Corvette.
1956/1957: Manufacturer - Westclox - These clocks looked very similar to the 53/55 clocks. One of the subtle visible differences is the clock knob.
1958/1962: Manufacturer - Westclox - The Corvette received a face life in 1958 with an all new instrument cluster and clock as well. A similar clock was also used in the 1955/1956 Chevrolet passenger car. These two clocks are interchangeable with the exception of some passenger car clocks manufactured by New Haven which has an aluminum housing. You will notice that the electrical clip is different and the small "F" & "S" on the face for the clock speed adjustment is reversed on these New Haven clocks.
1963/67: Manufacturer - Borg Instruments - With the presentation of the new Corvette Sting Ray, the instrument cluster and clock were re-designed. The "mid-year" clocks are broken into three groups with the main difference being the look of the face.
1968/82: Manufacturer - Borg Instrument - Basically all "shark style" Corvettes use the same type of clock. All were originally mechanical with the exception of the 1982 which was quartz for the factory. This group of clocks is broken up into seven groups with the differences being the look of the face, hands and length of the set stems.
