I recently bought a UN .900 Silver pocket watch. The case and dial both have apparently correct markings, with the serial number 527011 and the crest etc.

The movement on the other hand is not signed by Ulysse Nardin, and only is marked with the serial 403180 (even though it does look quite similar to some UN movements).

Before I send it back, I'd just like a quick once over to confirm it is a "frankenwatch" marriage of a legit case with a fake movement.

Please find attached relevant pictures.

Many thanks,
