It’s in very good looking & working condition. I have had it running for over 24 hours, it seems to keep good time. This is a windup watch, not battery. The watch has been well looked after over the years, it looks like it’s spent most of its life in the case & boxed. It’s all original, as shown in photos. Measures without crown = 3 cm by 3 cm . Any questions please just ask, I will do my best to answer. Thanks for looking.
