Scott Carpenter’s Gold Omega Speedmaster, a Piece of NASA History, Now For Sale via Wind Vintage

One of the reasons we love vintage watches is for the stories they tell. Yes, that’s a bit of a cliche, but every so often a watch comes to our attention that is truly historic, and really drives the point home. There are watches that hold personal meaning to their owners (family heirlooms passed down through the generations, for example), and watches that hold special and often outsize significance to small groups of collectors (like a Tiffany stamp on a vintage Rolex). But a watch like the Speedmaster Eric Wind listed for sale recently falls into another category altogether. This watch, worn by astronaut Scott Carpenter, exists at the place where watchmaking history and American history meet. It wouldn’t be out of place in a museum, but if you have the cash, it can be yours.  First, a little background on Carpenter, because the fact that this watch was his personal Speedmaster is a huge part of what makes it special, particularly to hardcore vintage watch enthusiasts. Carpenter was an American naval officer and test pilot who was selected as one of the original Mercury Seven astronauts 1959. After John Glenn, Carpenter was the second American to orbit the earth, and was a key figure in the early days of the space program when it both captured the imagination of the world and was arguably at its most dangerous.

Why do Watches Use Sapphire Crystals? A Brief History and a Few Altern

Watches differ greatly in their sizes, designs, capabilities, straps and bracelets, and even in the materials used to make their cases. The one element that nearly always seems to be present when we peruse watches’ specifications is the use of sapphire for the crystal (for the newest of newbies, that’s the round, glass window over the dial). Over a certain “luxury” price point, a sapphire crystal is not even seen as a benefit but the baseline standard, like tempered laminated glass in a car windshield. How did sapphire come to play this key supporting role in watch manufacturing, and what did watchmakers use before it came along? For that matter, what differentiates different types of sapphire crystals from each other? Which materials other than sapphire are still being used in the watch industry, and why? And is sapphire being used for anything else in horological circles besides crystals? What are the properties of sapphire? Believe it or not, that little lens over the dial of your watch is made from one of the hardest substances on Earth. It is one of two precious gemstones from the mineral variety corundum, the other being ruby. Corundum, a crystallized aluminum oxide, is clear in its purest state; sapphires and rubies receive their blue and red colors, respectively from impurities: traces of titanium, and iron in the former, and of chromium in the latter. Sapphire (above) has a ratio of 9 on the Mohs Hardness scale. Among minerals, only moissanite, a naturally...
