Have one nicely done Chopard Mille Miglia Grand Turismo XL non chrono with simple Asian 21J movement purchased some years ago that fails to work properly and is beyond repair. Tried to service it but it simply stops after some time. Want to find some decent replacement movement as the watch is very nicely done with fine details. Would clone ETA 2824 or 2836 fit? Or ETA 2824-2 or 2836-2 (as I can see on Silix page)? And, where can I buy a decent movement? Any advice would be highly appreciated...
