I am trying to locate an old style watch battery

The battery is close to 1 1/8 inch across on the positive side. It has a small tit like appendage coming out of the positive side that is probably the negative post. The battery is slightly thicker than a quarter.
The numbers 061179 are printed on the positive side.

The watch can be identified as a small pocket type watch with a small rectangle containing what I think is an LCD screen to display the time. The case is copper plated with shiny brass. The name on the watch is Sensor with a small + in the o of Sensor. Can you help me find a battery for this watch?
