Lose pivot on chronograph hand

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

      Epilame / Fixodrop

      By VWatchie · Posted

      Yes and no. I use Moebius 9501 synthetic grease and it is significantly runnier than the Moebius 9504 synthetic grease (and I assume Molykote DX) that I previously used. I haven't seen 9504 spread and it is in my opinion the best grease money can buy. However, my current method of cleaning doesn't remove it from the parts, so that's why I have decided to use the 9501 instead. I believe I read somewhere that Molykote DX too is difficult to clean off. Thinking about it, I'm pretty sure my 9501 grease which expired in June 2022 is runnier now than it was when it was new, but whether new or old it always needs to be stirred before use. So, that's why I treat the parts of the keyless works, cannon pinion, etc. with epilame. That was very thoughtful of you and something that had completely passed me by. Not sure what the epilame will do when it wears off in a non-oiled hole. Anyone?

      Rolex 2235 escape wheel jewel setting replacement

      By nevenbekriev · Posted

      No problem to replace the setting with the staking set. Press the new setting from inside, use flat face punch with hole. The punch must be wider than the setting, the hole to be as not to press at the stone, but only on the bush. Press by hand until the setting gets flush with the plate surface, so the punch must rest on it.

      Quarter repeater mainspring thickness

      By nevenbekriev · Posted

      Yes, the arbor usually makes about 3 to 3.5 turns. But usually spring takes 2/3 to 3/4 of the free space in barrel, not 1/2, so take it for the calcullations. This way the change in torque is smaller. I have a picture for You, this one is little older, but no mater

      Rolex 2235 escape wheel jewel setting replacement

      By noirrac1j · Posted

      I overhauled a ladies Rolex and noticed erratic performance so I stripped in down again and did fault finding. This is what I saw. The lower jewel (the one in the plate) is cracked and the hole is too big. Before discovering this, I stripped down and re-cleaned the main-plate (and parts) by hand with a fine natural fiber brush. I somehow missed the fault the first time and cannot understand how it was still running. Perhaps re-cleaning it dislodged some pieces of the jewel widening the hole? I don't know. Now I need to replace the jewel but don't have a Seitz tool. The Rolex part is 2130-0913 and the top and bottom are the same. The part comes complete in brass setting with KIF elastor spring and cap jewel. Note: I have never replaced a jewel. I do have a good vintage stacking set that I've used quite a bit.  Can I replace using a stacking set? Any suggestions would be greatly appreciated.
