Quartz watches - low battery

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

      It might help us if we knew which watch like model number.

      Movement inserted from crytal side

      By Zedster · Posted

      Hi, guys I have a bit of a predicament and hopefully, somebody can advise. I'm working on a Roamer MST 521 where the movement is extracted from the crystal side. I'm now at the final hurdle where I need to replace the movement back into its case but I'm not sure of the correct procedure. I still need to fit the hands but that's where the problem lies. If I insert the winding stem to test the hands for correct alignment I will need to turn the movement over to release the stem again it's the spring-loaded type and needs a small bit of force to push down but with the hands fitted, I don't think I can do this on a cushion without causing some damage to the hands and that's the last thing I want to do, this watch has already been a love-hate relationship and I'm so close to boxing this one off which I'm counting as my first major project.  The other option is to case the movement then fit the hands and hope everything is okay. I've already broken the original winding stem but managed to find a replacement, the last one in stock, so I'm a bit reluctant to keep removing it. Any suggestions would be appreciated.

      Main spring

      I would go for the dearer spring. You won't need to remove the spring from the carrier ring and then use a mainspring winder to get it into the barrel, for a start. Also that spring is closer to the needed dimensions, especially the length. The length plays a part in the mainsprings strength. If you double the length you will half the force (strength) of the spring and vice-versa. A spring with 20 mm less length would be about 7% shorter, so technically would be 7% more strength, but I find halving this number is closer to real-world findings, so the spring would be about 3 to 4% more strength/force. On a mainspring that ideally kicks out 300 degrees of amplitude, a 3% increase in amplitude would be 309 degrees. Increasing or decreasing the length of the mainspring will affect the power reserve to a greater or lesser degree. It depends how much shorter or longer it is.

      What tools does ebay have to offer this week.

      By Malocchio · Posted

      I recently bought this but not on ebay. I figured if I want something Japanese I better check Japanese auction sites since these don't seem to pop up on ebay. I paid 83 € plus shipping & taxes. I think it was pretty reasonable for a complete set in good condition.

      Did you take the friction pinion off the large driving wheel and grease it? Although, now that I think about it, that shouldn't have any effect on the free running of the train if the friction pinion isn't interacting withe minute wheel/setting wheel...
