This double-sided pocket watch is very unusual.
This watch movement is of very high quality and would have been intended for a large and heavy gold hunting case. It is possible that due to its unusual nature it was never sold and never left the Swiss manufacturer as a complete watch but simply put in what might be termed a ‘’working case’’.
