Thought some may find fascinating i sure did

here's a google extract

The Fall:
Although no one knows for sure when the Gibeon meteorite fell to earth, everyone agrees it was in prehistoric times; some speculate it was about 12,000 years ago. The strewn field it fell in is among the largest on earth, 70 miles wide by 230 miles long

The Slices
Most meteorites with a high iron content - such as the Gibeon Meteorite - were formed in the cores of asteroids at temperatures up to and over 2,500EF and were originally completely molten.
Very gradually - at a rate of perhaps 18-180EF per million years - the liquid metal cooled and began to crystallize. In cases where the percentage of nickel to iron in the cooling mixture was "just right," two alloys, Taenite and Kamacite, would form slightly different crystal structures which grew into and over each other.
The resulting intricate designs created by this intergrowth are called "Widmanstatten Figures" and are characteristic of many iron meteorites. Radiometric dating indicates the crystallization of Taenite and Kamacite in the Gibeon Meteorite took place more than 4 billion years ago.

Gibeon Meteorite Facts, Information and Description

Since it was first discovered in 1836 in Great Namaqualand, Namibia, Africa, more than 25 tons of Gibeon meteorites have been recovered and although export and sale was banned by the Namibian government, it is still one of the most commonly available meteorites on the market today. The Gibeon meteorites come from broken asteroid fragments or an exploded star and radiometric dating places the age at around 4 billion years old.

Gibeon meteorites are composed of iron, nickel and small amounts of cobalt and classified as a fine octahedrite iron meteorite. Some other minerals that may be found in the meteorite are chromite, deabreelite, enstatite, kamacite, taenite, troilite or tridymite.

Lines and patterns are the result of cooling in outer space over billions of years and etching slices with dilute nitric acid allow these patterns known as "Widmanstatten lines" to be more visible.

Until recent years, most Gibeon meteorites that were recovered weighed between 200 and 1100 pounds. One of the largest masses ever found weighed over 1400 pounds. Probably due to better metal detection equipment, many smaller specimens have been recovered recently.

When a meteorite enters the Earth's atmosphere, friction raises the surface temperature above its melting point. As the meteorite descends, it slows down, and the heat from friction decreases resulting in a thin layer of dark glass. The surface on some meteorite's may develop shallow pits during the entry process and these pits resemble thumb prints and are known as regmaglypts. Imagine bread dough that has been kneaded which leaves finger imprints in the dough ball.

Interesting read.

Beautiful watch, does this type of dial look the same on all examples or?

Here's an interesting fact............Did you know they only become meteorites when they land on the earth? Until that time, they are meteors.

This model is very nice, but is the so-called meteorite dial actually hewn from a meteorite?

INDEED !!!!!! The dial is hewn from an actual fragment of "Gibeon Meteorite" with no two dials being the same! each unique in its own right
