Quartz watches - low battery

[eezy]

Do all quartz movements indicate low battery with the customary second hand jump or do some keep going and losing time until the battery runs out?

In particular I have a Hattori in a watch which is 3 weeks old and in that time it has lost exactly 1 hour. It has 2 year warranty but postage would be more than what I paid for the watch. I'll change the battery and see what happens.

No, they don't all do this.

I suggest that you measure the battery before blaming it. It could be also a lose cannon pinion.

Hi  as jdm explained  not all watches exibit the sweep jumping as a low battery indicator, usually on better quality ones, the lower grade ones just either go down slowly or stop. Check the battery for the 1.55v if lower than 1.3 change it as some don't deliver the power. I have had them stop and a new battery fitted has been going a year later. but some times the watch its self is at fault being gummed up or dirty therefore the watch demands more of the battery witch fails quite quickly, canon pinion , sticky gear train , rotor bearings sticky, or dirty

Yep, battery checked, knackered and replaced. Looks ok for now. Thanks
