Quick Question: Squeezing Down Second Sweep Hole?

Dear all,

 

I am putting together a gift watch and have an undifferentiated Asian movement (I believe ETA clone) that looks to take a size 18 second sweep. I have a set of what I think are 120/90/20 or 120/90/22 hands from a practice movement that I want to strip and paint for the watch. The hour and minute hands fit nicely, however the second sweep is clearly too big.

 

I took my tweezers and squeezed the hole at three angles and made a very crude hexagon out of the second sweep hole. It now appears to fit and at least turns with the movement.

 

Has anyone tried this? It seems like it is destined to fail at some point. Do any of the following seem reasonable?

 

- Turn it upside down and shake vigorously, if it doesn't fall off let it be

- Put the sweep on the movement without other hands and squeeze hard with very fine nosed tweezers

- Put an incredibly small amount of some weak adhesive (rubber cement?) into the lumen of the sweep, install and wipe excess

 

This is definitely not Daniels level work, but the watch is a manual winder intended for a Father-of-the-groom who just wants a nice looking watch to be worn infrequently.

 

Thanks for any insight you may have,

 

Mute

Hi Mute,

 

While the fix you came up with may work for a while.. the problem is thehand only 'grips' the seconds pinion at a few points, as opposed to a correctly sized hand with fits all the way round and for the length of the tube.

 

If not securely fixed, the hand may not stay level and will interfere with the other hands/dial.

 

If its your own watch, hell, wear it and fix it as you go. But if you're giving it as a present then I think you should get a replacement hand.

 

just my $0.02.

It has been mentioned before in the forum. You are better to use a lathe collet or a pin vice to reduce the diameter. Just remember that a wee squeeze can go a long way.

      We need to identify the movement to help you, but the oldest of these Rolco watches use Aegler-Rebberg movements that lack a calibre number and are very difficult to identify. You may end up having to make or modify a stem to fit . Post pictures of both sides of the movement when you have it and the size of the movement and hopefully it’s one that has a calibre number.  Gruen used a lot of the same Aegler movements at the time and it’s worth comparing your movement with those if you can’t find it labeled as an Aegler or Rolex/Rolco calibre. Best Regards, Mark

      How to remove shock settings from Smiths 512 movement

      By Mercurial · Posted

      The triple lobed spring, as you suggest needs to be rotated to remove it or replace it. Suitably shaped pegwood should suffice, but tools (shaped as you describe) for the purpose also exist.  If you have an assorted of replacement springs, a trilobe style KIF spring of the right size might fit.  The other spring securing the jewel also needs rotating. There is a slight opening in the setting at about the 5 o’clock position in your photo and one side of the spring should be able to be removed  there when rotated into position.  Hope that helps, Mark

      As an update, it transpired the setting on the balance side, with the jewel had one flat end and one curved. When I rotated it enough it popped out. The chaton was entirely conical and a tricky customer but once lubricated and dropped back in I put the flat edge in first and poked it in with the peg wood tool mentioned above (I made it with flattening off the end then sizing with a pencil sharpener before poking a hole in the end) then rotated and it went in well.    For the other side, magnet searching for the spring has been fruitless.    thanks for the link to the other thread

      Omega Split stem issue (will not go back in)

      By Rustinbox · Posted

      Thank you. It didn’t look rusty. For sure old.    Female part was inside the movement, and when I pushed male part, it got broken. I didn’t apply grease. Here is the photo.      Could it be that male part is too thick for some reason?
