This is the latest addition to my growing watch collection. It's a vintage Swiss made Fortis Sports Tuxedo hand winding watch, which I got at a bargain on eBay. Like any stuff you buy over eBay, it is a bit of a gamble but this time it paid off. The watch has kept good time since I last set it this morning (as soon as I opened up the package).
I am still new to horology or the art or science of measuring time but I am learning a lot. I learnt that the company is based in Grenchen, Switzerland that was founded by Walter Vogt in 1912. Working with John Harwood, the British inventor of the automatic wristwatch, Fortis came out with the first self-winding (automatic) wristwatch, the Harwood Automatic in 1926. They are also the official supplier of watches to the Russian space agency.
About the watch - surprisingly for a company which has been around for more than a century, there was very little information about the Watch. As mentioned earlier, it has a hand winding movement and 17 Jewels. It is encased in a stainless steel case with an after market black leather strap. The watch measures 36mm (without the crown)
The description on eBay said that the watch crystal is Sapphire crystal but I found out that it is actually clear acrylic glass. Another mistake in the listing was the age of the watch. It was mentioned as modern (2000s) but I found out that it is a vintage watch (1971-1983). It might actually be older than I am.
