1827 V&C Jump Hours

Very nice report on VC history

Thanks Dean, I am beginning to fall for the art deco style. The Gustave Sandoz pocket watch you show flows through many years of VC's DNA. I think any collector of vintage VC could be happy in having one of these examples. I especially like the Cart QP wi...

A few examples...
