I am assuming this is a magnet-set watch [in an auto-setter this symptom suggests a fault in the clock chip itself, which would be unrepairable]. Rather than removing the time demand switch, I would cut one lead [effectively removing the switch from the circuit]. If the watch begins operating properly [you can simulate the operation of the switch by shorting across the leads with a pair of tweezers], just cut the other lead and replace the switch. If the problem persists, the switch is clearly not the source, and we are probably back to a chip fault, and a scrap module. I have a Ladies Cushion with the same problem, unfortunately not fixable, but it shows the problem is not limited to any particular model.
