I have a stainless steel, original gen (series 0) watch that has just had the back fall out, damaging the connecting cable as it did so. It is out of warranty (even the extended warranty for backs falling out), so Apple says it will be AU$350 to return it for repair or (more likely) replacement. It is definitely not worth paying that much for a S0, but I doubt Apple still have S0 stock so I suspect I might end up with a slight upgrade. Does anyone know for sure? Would I end up with an S1 or maybe even S2?
