ComLink Wristwatch

Step 1

Carefully fit the tabs of the Watch Glass into the matching slots in the face of the Watch Case.

Make sure this is installed in the correct orientation, as shown. I recommend fitting the upper tabs of the Glass into the Case first, then gently popping the opposite tabs into place:

Step 2

Fit the Dial (45E) and Speaker (45D) into the matching openings on the inside of the Watch Case.

There is a small notch in each part that matches a tab around each opening of the Case. Be sure to insert the correct parts in each hole, as shown:

Step 3

Fit the thinner ends of the three Adjustment Button into the matching holes on the sides of the Watch Case, as shown.

There is one hole on the left side of the Case:

And, there are two holes on the right side of the Case:

Step 4

Slide a CR2032 button-cell battery (not included with the model) into the holder on the back of the Electronic Board with Display.

I recommend only handling circuit boards like this by the edges of the Board to prevent damaging any of the delicate components. Make sure the positive (+) side of this battery is facing away from the Board, as shown:

Fit this Electronic Board assembly down inside the Watch Case. Ensure the three switches on the sides of the Board fit inside the Adjustment Buttons, as shown.

You may need to use a small flathead screwdriver to move the Adjustment Buttons away from the Board to fit it fully into the Case:

Secure the Electronic Board to the Watch Case with one (1) FP screw:

NOTE: While this step completes the ‘build’ portion of this stage, the magazine instructions do continue on to testing all of our K.I.T.T. electronics. However, since the PCB of our watch is still exposed, I chose to first skip ahead and complete the next stage which closes up the watch. Then, I wrote up a dedicated post about this first Electrics Test including how to set up the watch.


This ComLink wristwatch is actually quite accurate to the one used in the Knight Rider television series. The actual watch prop used on the show began life as a LCD AM Radio Watch which had its bezel label changed out. The Dial on our watch even shows the details of the AM tuning dial that was present on the real thing. Keep this ComLink assembly nearby as we will finish it in the next stage.
