Hi, I believe the watch maybe a Homage watch, The movement looks to be ETA 6497 but does not have a regulator on the balance cock. I think it may not be a genuine Swiss movement. As far as I know Nivrel uses genuine Swiss ETA 6497 movements are marked Swiss Made on the dial at the six o'clock position. I don not know much about Nivrel watches but that may be something you may want to research further.
