The watch is now working properly and when compared to my reference atomic clock it is lagging by approximately 1 nanosecond every day i cant say if this is due to the battery

Next part of this review will be the longevity of the battery i wonder if it will be affected by how many times i looked at my watch

I cannot count the hours i spent looking at myself on this perfectly smooth surface

Next it fits quite well in the battery compartment i compared it to the original battery and it was only 1 micrometer smaller in size
