This Is A Beauty. J.sewill Pocket Watch.


Recommended Posts

This came in with a broken staff. Somebody had already removed the broken piece which is now lost so it will be a small challenge as I usually use the old staff as a guide.

Excellent, I re-pivoted a Goliath watch a couple of months back and it was a right fiddly affair.

Are you going to make a video of the manufacture?

 

Not on this occasion as I don't have long to complete the job. I will take some pics though.

Is this strictly a "Time of Day" watch, Mark? There's an awful lot of extra gears and stuff on this thing! I'm also curious on the sub seconds chapter position on the dial.

 

I think it is truly a fascinating timepiece!

 

Thanks for sharing...

Did you use a carbide spade drill?

I use a 0.5mm solid carbide twist drill, it was like mating hedgehogs. The pinion was 1.96mm long x 0.5mm diameter reduced to 0.14mm diameter x 0.5mm long to fit the jewel.

Finding the centre has to be the trickiest part!

I squared off the end of the shaft in my lathe using a carbide lathe tool the using the same tool dished the end of the shaft. I then spotted the end with a 1mm carbide drill before using the 0.5 drill.

Removed a lot of material before parting off:

Trying the roller for size:

Now using a pivot file to fine tune the taper so that the roller will fit snug:

Now I have my roughed out piece I can start polishing and grinding the pivots down to size. Lower pivot is about double what I need in length as I do not know how long it should be yet:

Looking good. Finished today or tomorrow?

Not today. I have to strip the watch and service it.

 

Wrapping it up for today. Heres a couple more pics.

 

I'v mounted the staff on the wheel so that I can use the Jacot tool. Grinding the pivots to size with my pivot file:

I'm about half way there:

    • 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  
    • Onlly a pro's eye would notice that OH, you've still got it old fella 🙂
    • 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
    • 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?
