My Monnin cased 980 stopped last night, I assumed time for a battery change. I thought I had some spares and had at some point made a note in my diary that it takes a Renata 344 (SR1136SW) but I was surprised to open the case and find an SR43SW inside. The spare 344 I had fitted but didn't work, possibly old and flat, but I am confused. Does anyone know what the correct battery is before I order more? Couldn't find the answer here or on Google
Many thanks
