At the begging of the week I’ve lost someone that was dear to me. So the week started like a real shit! Anyway!

Today I was at home and remembered that I’ve a pocket watch movement that was selling that wasn’t working.

Until today I’ve never disassembled a watch mechanism, but I thought to my self: let’s give it a try.

This is the Eberhard caliber I was selling


I followed a tutorial that is posted at HF but for a 6498 .

Put the movement on the movement holder and start the work.

After disassembly the movement the problem was the winding spring. It was out of its place. Put the spring in place assembled the movement and it came back to life!



Now that the watch is back, and because it came back to life at this particular week, I’m going to give him a second life, my desk watch

Now I just need a stem for this guy. Does anyone knows were I can find one?

Have You tried 6497 stem? This thing is a Unitas (I don't remember the cal no), so it might just work by chance...

Sorry for your loss!

Seems like the only solution is trying a 6497/8 stem to begin with.

Easiest way is to remove the dial and adapt the stem in steps, clutch wheel, winding pinion and last the groove where the setting lever goes in.

I don't know the caliber either. The regulator arm is heading for freedom?

The regulator arm is not going anywhere



I tried the 6497/8 stem but didn’t work. The sliding pinion is thinner than the stem.

Who has the skills here at the HF that can work the stem?

I know, it probably just ended up there while you worked on the movement.

The square portion will need attention?

I have a selection of stems, and I can probably make one of them work.

Ever tried Ranfft for movement identification?
If this is a UNITAS base, there is only a finite choice

Often Ranfft also gives you the Flume catalog number for the stem.

I actually looked at the site, but no luck. One must possibly look for information on Eberhard and go on from there.

Perhaps: https://www.eberhard-co-watches.ch/en/

Who knows, they may be able to help, Longines does offer archive information and these may as well.

I’ve been searching for the caliber name for a couple of months.

Here’s the 6498 stem and the movement parts.

Grab a 6497 stem (or Molnija stem - this will probably work better just because Molnija has a smaller square) and a needle file and have a go at it. Even if at first You fail, then these stems are cheap enough to learn.
My very very first build had a 6497 stem modified to fit Buren Grand Prix movement...

Oh yeah, that stem looks a bit fat for those parts.
