Can you post a few more pictures? It might have come from a housing that was made of 10 k gold. The housing with a clock in it was a desk clock and they were given to long term employees or for just general type gifts.

The clock itself, if it is mechanical, was likely made in Germany. If it is a quartz that is run by a AA battery it is really not worth much except for the face plate.

Photos of the back and/or any markings on the back would be very helpful.
