I would be somewhat shocked if anyone actually knew what model# their Benrus electronic watch was. What movement does it have inside? If it is an LIP movement it likely needs a 301 battery and if it was an ESA movement it likely uses a 344 or 389

If it didn't start up with the new 344 battery installed then the movement is likely dead. Many, if not most, of the Technipower watches used the ESA 9154 movement and while they are fairly reliable, they did have their issues. Perhaps someone here can recommend a repair shop for these watches? I checked my 3 electronic watches and two of them have an ESA 9154. One had a 344 battery and the other has a 386 and both run / keep time. The other has a PUV 907 that uses a 303 battery.

I have a Benrus electronic technipower watch. The # on the back is 6497. What do I need for a battery?
Thanks.

IF you read the previous posts, you would realize that we need to know what movement is inside your watch, not the case number.
