Lose pivot on chronograph hand


IFELL

Recommended Posts

Hi all,

as I was servicing a chronograph movement Landeron 248, when removing the hands the chronograph seconds hand popped into two pieces (shaft and the hand).

I was able to put the hand onto the shaft, but now the diameter of the shaft is a bit smaller so the hand slips and turnes on the shaft if I hold it in tweezers and blow air on it.

What is the way to fix it? I do not have a staking set and I am thinking about broaches, but not sure if cutting or smoothing broaches would do the trick.

Please help. Thanks.

Are you saying that the hand has detached from  its tube that attaches it to minute wheel pivot ? or are you saying that the hand is loose on the minute wheel pivot ? cutting and smoothing broaches would be of no use, the tubes are riveted in place when manufactured.

This repairer had to solder a tube back into place,

maybe a loctite type glue carefully applied would do the job or look on ebay for a new hand they do turn up
