These gearboxes are a new product and have been carefully developed to exceed the OEM specifications for increased longevity. Not to be confused with earlier, poor quality versions.

When first introduced these gearboxes had an incorrect cable fitting, these were withdrawn & re-made. Now they are top quality.

All these instruments are slightly deeper than the Smiths clocks so won't fit inside the A65 rubber binnacle. They do fit the T120/140 binnacle. From the underside of the chrome rim to the base is 45MM (1 3/4"). The diameter of the body is 80MM (3 1/8") the diameter of the rim is 87MM (3 7/16")

This the same size, or slightly shallower than the Veglia T140 instruments.
