All was going great when I diagnosed that the canon pinion was in need of tightening. I dismantled very carefully and thought I would give it a service. Whilst rebuilding, again very methodically and carefully, the darned pinion on the 4th wheel just flipped! To try and console myself I imagined this was due to the age and wear/tear, still mightily frustrating. It still works well and keeps good time but alas no seconds hand fitted. It's an ABERCROMBIE AND FITCH (ALSTATER) fitted with a Schild 1568 movement. Can anyone tell me where I can get a replacement 4th wheel, pretty please? Agreat forum with some very educated contributors nice to join and read you all. Thanks!
