··Carpe horologium!Wasn't the speedmaster meteorite dial, made from a meteorite found in namibia?
A farmer was ploughing his field with an ox sometime around 1918, and his plough hit the estimated 66 ton mass, now known as the 'Hoba'. I'm not sure if Omega sourced its dial from the 'Hoba' itself, or another specimen that was part of the same fall...but it has an interesting history:
The Hoba meteorite is thought to have fallen more recently than 80,000 years ago. It is inferred that the Earth's atmosphere slowed the object to the point that it fell to the surface at terminal velocity, thereby remaining intact and causing little excavation. Assuming a drag coefficient of about 1.3, the meteor would have been slowed to a mere 716 miles per hour (320 metres per second (1,000 ft/s); contrast this with typical orbital speeds of several km/s). The meteorite is unusual in that it is flat on both major surfaces, possibly causing it to have skipped across the top of the atmosphere in the way a flat stone skips on water. (from Wikipedia)
