Just spent the best part of the evening getting my Delux clock to work :roll: Ive had this for ages a '70 model, that didnt work but paid next to nothing for it.
These early clocks are pretty straight forward to work on as the workings are housed in the plastic cover removable with 3 x 5mm nuts. The mechanism is basic clockwork using a spring and a flywheel with the 12V supply literally recoiling the spring when the contacts close (see contacts top let of the below pic). Basically due to build-up of grime the contacts dont quite make when the spring is at its weakest just before the contacts make to re-coil, so by spraying liberally with electrical contact cleaner will usually free everything up and do the job.
If this doesnt sort your clock then another common fault is dry solder joins on the relay connections, finally there is a solder 'fuse' this melts if the clock has a short and breaks the supply. Special low melt temp solder is required for this, if you use standard solder you run the risk of frying your clock should the same fault occure.
