im looking to invest in a nice (but not too nice) wattch winder for a friends birthday. I think this will be a great addition to his growing collection. So far, the Volta Signature double watch winder, carbon fiber really stands out to me. But then again,I don't know what I'm looking for. Does anyone have a little more information than whats given online? Like, the life span, is it worth the money spent? Or is there a better, in the same price range, line?
