308 GT4 Clock Set Time Knob Repair (Veglia 24 3003)

The knob to set the time on my EU Series 1 GT4 clock (Veglia 24 3003) did not work anymore and the minute hand was stuck, so i had a look if it can be repaired. From the Veglia clocks i've worked on so far, either the plastic axle of the large cog below the 0500 position or the small cog on the set knob axle was broken. As an easy check, if the set knob button does not work and the minute hand won't move anymore then the axle of the large cog is broken. If the minute hand still works then the small cog on the set knob axle is gone.

If you are lucky, the plastic axle of the large cog is broken and the small cog on the knob axle is still ok, as the broken axle can be replaced relatively easily. Remove the internals from the housing, gently remove the hands by pulling them upwards, then remove the set knob.
Remove the dial, and the upper plastic assembly of the clock which is held in place by three black screws. Drill a 1.5mm hole where the old broken axle was and press fit in a new 1.5 mm steel or brass axle with a length of 6.4mm. (The factory axle has a diameter of 1.4mm but i had a hard time to find 1.4mm steel or brass wire so went with 1.5mm)
Take care that the lower end of the new axle sits flush with the impression on the bottom side of the top plastic assembly so it won't interfere with the two small cogs there. Extend the axle hole of the large cog from 1.4 mm to 1.55-1.6 mm and reassemble everything.

Not sure if this is common knowledge, but the Fiat 124 Veglia Quarzo clock (part number 24 3012) is a direct plug and play replacement for the GT4 clock. Both clocks are nearly identical (except some components on the PCB and the front bezel), and the GT4s dial/hands/set knob/bezel/glass can be directly transferred to the Veglia Fiat 124 clock. See photo below of the Fiat 124 clock (left) and GT4 clock (right).

What i did was to first remove the screws from the front instrument panel, then pull the instrument panel a bit forward. Put a towel on top of the steering wheel column first to avoid damaging any of the instruments. Take extra care not to bend the clocks set knob axle in the process.

Then i removed the Speedo by first removing the two lock nuts by hand from below (bit tight but it worked for me), then pulled out the Speedo to the side and removed the AMP connector for the wiring and the knob/wire for resetting the ODO.
You then have access to the clock via the Speedo hole in the dashboard and can easily remove and reinstall it.
