omega seamaster polaris chronograph quartz

[keflin2612]

HI folks,

I want to change the battery in a omega seamaster polaris chronograph quartz, I purchased a Renata 395 battery for it as I thought this was the correct battery but when I opened the case up it was fitted with a Renata 394.
Could someone verify which one is correct please.
Cheers.

Kev.

Quite possibly neither one. Since your watch was fitted  with a 9.5mm x 3.6mm battery, that should be the right size, please check visually or post a picture if unsure. The 395 instead is 2.7mm tall which could be too little, hence the wrong size.

That being said since your watch is a chronograph it is best to fit an high drain battery type, of which neither 394 or 395 are. They are referenced in the chart below, have a look.

Thanks for your help, I have put the two batteries together and looking at them you are right the 395 is far too small.
