Repairing a watch feels similar to dealing with code to me:
- observing to see how/why certain watch components/chunks of code work and interact with each other - analyzing performance - disassembling and cleaning parts/"cleaning" code - troubleshooting why something isn't working - repairing faults caused by the previous watchmaker/developer
I highly recommend it to anyone needing something physical to do after a day spent staring at a screen. Stare at a watch instead!
