Have any of the Waltham Model 72 experts seen a gold pallet fork before on a 72? It is on a late"Royal" grade around 4 million serial number. Not marked NonMagnetic. I've not taken down to many 72's, but have read just about everyting I could find about them, but never has a gold pallet fork been mentioned......just curious,
Harold

I've never seen that on a '72, but I've had several '83s in that general SN range that had that pallet forks and roller tables that were that same color.

The first time I saw one, I thought it was from someone heating the roller table up too hot replacing the roller jewel. I've seen it enough times on enough watches from different sources, however, that I'm doubting that.

I'm not sure what the material is, but I don't think it's gold.

Later double roller Walthams also had the impulse roller made of a similarly colored material.

I checked a Waltham Parts book. It lists many versions but makes no mention of material composition. This suggests that ther ewer eniether gold nor gilt factory pallet forks.

Ben, I just checked, the roller table is a matching color, I now know that both the roller table and fork do not just have a gilt finish, I scratched the bottom side of the fork, it's rather soft, either gold or brass for sure. Since brass over a period of time turns dark, and gold doesn't, this pallet fork still being bright and shiny led me to believe it was gold. What would be the advantage or reason to NOT using a steel pallet fork and roller table if a regular blue hairspring was used, It certainly wouldn't qualify as a non-magnetic version.

Harold, the non-magnetic materials were as you describe for the non-magnetic 72 models. They did not necessarily mark the plates for the non-magnetic models. If the plates are marked the materials should be there, but the reverse is not necessarily true.

I do not recall seeing any non-magnetic parts listed in the parts list, but I have not done a thorough search. They certainly exist in the watches and predate Paillard non-magnetic hairsprings.
