Does a meteorite dial patina?

Hi everyone,

This is my first post to hopefully contribute in a small way to the amazing discourse around this forum.

As a Speedmaster Apollo-Soyuz LE “Speedyorite” owner, this question has bugged me for some time and I wonder whether anyone else already has some answers.

I know meteorites that land on our planet survived the cold vacuum of space for potentially billions of years, then entry to our atmosphere, striking the ground at great speed and finally our weather extremes for perhaps thousands of years, so they must be tough. But, when you slice a piece of Gibeon meteorite into thin wafers to produce watch dials and then oxidise the surface, as was done with the Speedyorite to produce the dark grey colour over most of the dial (the subdials are the natural colour of the meteorite), how will that process affect the crystal structure and the surface colour and finish over time? Is the surface oxidation layer likely to change colour? Will slicing up the meteorite into thin wafers have somehow weakened the crystal structure at the surface? Or, will the Speedyorite be a rare patina-less watch?

Cheers

Chocolate dials of the future.

I was thinking they would age into a shade of deep purple with contrasting notes of sky blue.

Damn, if that could really happen, I might have to buy one.

I didn't even know these existed (Speedyorites, not meteorites of course). I don't presume there are a whole lot of them floating out there. And their prices must really be astronomical.

Seems to be around 10k for the Soyuz and they also have the 44mm meteorites in co-axial

It was a limited series of 1975 pieces.

Probably less Deep Purple and more Metallica...next watch for @Mad Dog maybe😎

A 200,000 year old vintage speedy - that would be something to hang around for!

Yes. Sorry for any confusion I meant $10,000 for the Soyuz

The metoerorite dial like the Rolex ones are made from a specific meteorite that fell in Africa. It should never rust. The large crystals and non rusting alloy are fairly unique.

All meteorites, even Gibeon, will rust, as they all contain iron. Meteorites used in jewelry and for display are etched with acid to bring out the pattern, then sealed with Renaissance wax/lacquer/some proprietary formulation to retard oxidation. It can still occur.

I was under the impression Gibeon was highly oxidation resistant compared to other ores with the Widmanstätten pattern. Mostly due to the high cobalt in the ore. But yes it can rust, I’ve seen older pieces of jewelry/findings made from this with no protection and still show the pattern after etching for years.

This is why that look is somewhat common but only Gibeon is used for dials, and now very very hard to source due to it no longer being exported from Namibia.

I collect meteorites and basically there're 3 kinds of meteorite:
Stone ( Achondrites = Lunar & Mars ) ( most are Chondrites showing chondrules grains )
Iron ( most show the Widmanstätten patterns upon etching... exception are the Ataxites ) ( these rust even in controlled environment ! )
Iron-stone ( among these are the Pallasites which contain the lovely olivine peridot crystals )
....
Although the dial sits protected underneath the glass, it will last long but eventually deteriorate over time... nothing lasts forever 👎

.
In fact You're right... about the number of watches and the number of asteroids
All asteroids combined out of the belt between Mars & Jupiter could not fill a ball the size of the Moon... but as we recently learned, sometimes we get an ET-visitor from beyond our Solar System (e.g. the cigar-shaped ‘asteroid’ discovered in October 2017 was an interstellar lump of ice ... an extra-solar object passing through our neighborhood)

Well, none of this sounds like deep purple or sky blue. I admit I’m disappointed. Sounds like it could be stunning.

The Gibeon is 92% Fe (Wikipedia) so unless the subdials have been clear-coated with a protective layer, presume they would be more likely than the oxidised grey parts of the dial to change colour over time ??
