Bump

 

Prob should be a 371

 

That watch should have a Ronda 515 HH6 movement which takes a 371 battery

 

Thankyou... could the wrong battery cause the problem I described about missing time?

 

I recently brought my Luminox 3000/3900 to the booth at the mall for a battery replacement. Ever since it skips time depending on how the watch is worn. I opened it up to check and the battery doesn't seem to fit in correctly. I'm assuming he put a slightly wrong battery? It is a Renata 393. I do not have the original battery so I do not know what the actual size is. From what I've found here it looks like a Renata 395 should be correct? Does anyone know the right battery? Thanks in Advance!

It takes a 395 battery

 

I agree that it takes the 395 battery. Otherwise known as a SR927SW. Get it changed to the correct battery immediately. Your issue should clear up.

 

Similar issues: 395 fixed mine. Luminox service (Saltzmans) couldn't be bothered to fix it just sent it back after charging me.
