  1. Hello, It's been a while since I've posted but I have an issue that's perplexed me! About ten months ago, I repaired and serviced a rare ETA 2832 movement with a day date calendar mechanism. The watch worked fine until recently when the day wheel advanced half way and then got stuck. Having had it back on the bench and done a partial strip-down, I have re-engaged the day wheel, which now turns freely through all days in the crown/stem corrector position (as does the date wheel when turning in the opposite direction) but when moving the hands forward through 24 hours, the date wheel advances but the day wheel will not. I have carefully examined the day jumper mechanism and note that as the calendar wheel rotates and the arm engages the teeth and rotates the date wheel, nothing seems to be engaging to move the day wheel forward. I have added a few photos which may help to identify the problem. I have annotated with a red arrow, the lever which I think is supposed to advance the day wheel but doesn't engage at the calendar wheel teeth (if indeed this is what it's supposed to do). Any ideas of what I may have missed here? Thanks

  3. Hello, I've been struggling for two evenings now to fit the train bridge on this ETA 2832. Every time it looks like all pivots are aligned through the jewel holes and I begin tightening the bridge, the wheels begin locking up. On closer examination, it looks to me like the 4th wheel is not seating flush against the centre tube as shown in one of my photos. I believe this because the pinion on the 4th wheel is higher than that of the escape wheel, and equally about the same measurement out between the 4th wheel and the 3rd wheel pinion, which is lower. It also looks like the 4th wheel is fouling under the train bridge. In your opinion, would my suspicion be correct or should the 4th wheel's pinion rest approx. 1 to 1.5mm above the flange of the centre tube. If it should be flush, do you have any tips to seating it as such? I have obviously tried carefully wriggling it under light pressure without luck. I've added an extra photo showing the placed wheels during disassembly to give some context. Thanks in advance
  4. Hello, I have been asked by my stepfather to service his Sanford Bros HF 36000 automatic watch bought new in 1977. On starting work, I noticed its an ETA 2832 but on looking for the technical sheet, I can't find one anywhere. Perhaps it is a rare movement but maybe there's an equivalent document I can use. My first main concern after removing the rotor is how to remove the auto-wind assembly - looks quite complicated and this is only my second attempt at an automatic movement. I've added a few photos for reference. Of interest, Sanford Bros was a small watchmaking company in the '70s based at 321/323 Oxford Street, London W1. He still has the original sales invoice! Would anybody be able to point me in the right direction please? Many thanks
