This adapter is the solution to the problem of the discontinued Rayovac RW-25 or Eveready 355 battery. The adapter has the outer dimensions of the Rayovac RW-25 or Eveready 355 cell and accepts LR44, 357, or 303 batteries. The LR44, 357, and 303 cell produces the volts that are needed for your watch, while the adapter replaces the original dimensions.

The adapters will replace the Eveready 355 or Rayovac RW25 batteries that were used in the original Pulsar & Hamilton watches of the 1970s, such as the P1 model 2800, the P2 one-button models, and the P2-Date II & P3 Date-Command models. The adapters can also be used in the Omega TC-1,TC-2 & TC-3 models as well as the Hamilton QED one-button and two-button models.

The last photo is an example and shows the adapters being used in a Hamilton QED two button model watch. No adjustment or modification to your watch is needed.
