Attention hand support.
The increasing number of returns of ETA 955.xxx and 956.xxx movements has prompted us to draw your attention to the issue of hand support:
When positioning the hands, please make sure that the movements are properly supported on the underside.
Without the support of the hands, you risk bending the gear train bridge and thus a possible spinning of the gear train. The wheels will then not mesh correctly.
The following universal movement holders with adjustable support screw are suitable for this purpose.
