The RW56 LM 11.6 3.6 343 RW56 3 MR42 218 B 509 is a 1.35 volt mercury no longer made but replaced by the 344 SR1132SW the voltage difference may or may not affect performance. Accutron models using the 1.35 cells should not be operated with a 1.55 volt replacement except as an experiment that it will keep the correct time. A diode can be inserted in the watch to lower the 1.55 to safe 1.35 and experts can be found that do this.

The 344 or SR1136SW is used by Accutron watches as a 343 or MR42 replacement. Perfect in some Accutron 218, Accutron 230, Accutron 224, and Accutron 219 or the Omega f300. Mercury batteries have been outlawed because of toxicity and environmental concerns and are no longer available. The 1.35 cell watches should not be operated with a 1.55 volt replacement except as an experiment that the watch will function with the slight voltage increase, as sometimes happens.
