Another day, another bumper 😉 This one travelled all the way from Norway, and Anders sent it over.
The luminous dots on the dial are missing, and he would like those restored, the movement needs a service, and a new crown…
Upon opening the case, I notice that someone has put lead into the groove where the gasket goes. Very strange, and I can’t make any sense of that (yet)…
On top of that, there is a hard plastic gasket which looks a bit home grown. The bells don’t ring yet, maybe you know already what’s going on!
I carefully clean out the lead from the case.
On the bottom plate, the set lever spring is broken and needs replacing.
The gear train is visible with the train bridge removed.
The mainspring is of the old type, and I will put in a stainless steel mainspring.
All ready for the cleaning machine.
The new mainspring is ready to be put into the barrel. I got a batch of 5 NOS, and I only have one left…
The balance jewels go back in, and the cap jewel gets a tiny drop of oil.
The basic movement is back together and ticking.
All looking nice and tidy. There is a tiny bit of oxidisation marks on the click wheel, but that’s to be expected on a movement that age.
The new set lever spring looks nice.
David Bill and Sons has done another great job on the luminous dots.
I case the movement, and make the final adjustment.
Back together, and I notice that the oscillating weight hits against the case back. Now I know why the lead and plastic gasket were in the back!
The old crown and winding stem need replacing – the old one is still in place in this photo.
Anders provided the new part, that he found in France.
With the new crown and winding stem, I test if the watch is water resistant. The result is “a bit”, which is normal for a vintage watch. The gasket surfaces are always a bit pitted and worn, so even with new gaskets, the watches are never completely water resistant.
Back together and looking beautiful.That looks great, too!
