I'm new to this forum, I hope that anyone who's an expert or a keen collector can help me here...
I just bought this 18K small pocket watch (31mm diameter of the case), with a cylinder movement signed Vachero & Constantin on movement and case.
The case is a thick gauge 18K solid gold sponsor-marked PF and with another mark above.
The dust cover looks also made of the same grade gold however it is not marked for gold anywhere but it's inscribed Vachero & Constantin and with the description of the movement.
It looks all genuine but would appreciate any opinion from collectors on this site, as I could still return the watch if advised on it not being genuine.
