• Most of them are Ronda movements. You can usually clean the bearings and lubricate them without having to fully disassemble. However, you need a proper quartz testing machine like a Witschi to prove that the current draw has dropped down to within the manufacturer’s spec.

  • It stopped completely last night... shall I take off the battery and send it somewhere local that deals with quartz movements?

  • You could do, but I’d be careful in case someone decides to charge you for a full clean/service which is pointless. You could ask for a quote for a movement replacement, or even provide the spare movement by buying one yourself. If you don’t get any reasonable estimates then wait a month or two and I may be able to take a look (I’ve done my BHI quartz exams, and these are fairly simple).
