Veglia Borletti Analogue Clock For RHD 141A Fiat Panda (Spares Or Repair)

Veglia Borletti Analogue Clock For RHD 141A 1st Generation Mk2 Fiat Panda (Spares Or Repair). Casing in good condition and adjuster works but looses time and then stops after a couple of days even though you can still hear mechanisms working. Seems to retain time if you put some mild pressure on adjuster knob so maybe a cog inside worn or dislodged? There are 2 brass nuts on back and 3 retaining clips on clock face suggesting the unit can be opened but I’m reluctant to meddle!
