·Zenith parts can be a complete minefield, especially the early el Primero parts. What you need is time, patience AND a way in. Zenith can make, pretty near, any part for someone who has that way in. The easiest way is through the parts manager at your nearest LVMH service centre - if you can get hold of him. He can get the parts but is not allowed to sell them outside of the Zenith approved watchmaker chain (and that is not a published list). These approved watchmakers can also get the parts via the LVMH service centre, so if you find one of these watchmakers, treat him like your best friend. This gives you two options: either you have to convince the LVMH centre to do, just the work you want - or get them to service the watch at the same time or, the same with the approved watchmaker.
It can take several weeks for Zenith to confirm if they have the parts or if they are prepared to make them and then it can take a couple of months for the parts to turn up. Be prepared to pay a lot for these parts.
Thanks very much for the information Stewart; its just what the doctor ordered.
I'm hoping that my watch maker can first get the watch working. I will then look at getting the hands sorted.
I have also sourced an original GF bracelet which is en route from Turkey. I will probably need end links for it.
