missing Centre Cap Jewels......

I recently bought a pre-loved swiss DSN Ultimate Fiddy and on closer examination i noticed that the centre Cap Jewels was missing....i guess it is needed for watch longevity so would it be hard to get and fit a new one?

thanks in advance

If I was a betting man, I would say someone has upgraded this watch with the H3 cannon pin, and when they did this, they did not use the correct tool for the installation. Instead of applying the pressure on the great wheel pivot, they applied it on the jewel and it popped out of it's setting and this is why it's missing...

Yes it MUST be in place for the watch to run, do NOT wind the watch in this condition, or you risk the great wheel disengaging from the mainspring, and this can cause a lot of damage.

The fix requires the bridge to be removed, and a new jewel pressed in place with a Jewel press. As with any watch work, trying to do it without the correct tooling will only cause more damage.

It should be an easy fix for any local watchsmith.

Thanks Rob, you might see this watch again in the new year or when your feeling better.
