The battery clock that snuggly fits into the control panel above the habitation door of our 2019 B674 SL has stopped working (yes changed the battery!). As it is held in position simply by the tight fit,diameter of the rear mechanism, I need an exact replacement. Cannot wait 6 months for Hymer to respond any thoughts? Actually will seem like longer as the clock doesn’t work! Thank you and apologies it’s not such a hardship as other issues for some on here.
